The first ten seconds are where a best man speech lives or dies. Not the middle. Not the big heartfelt finish. The opening. If you nail that part, the room relaxes, the groom stops bracing for impact, and you suddenly look like you have this under control. If you are wondering how to start a best man speech without sounding stiff, cringey or half-cut, the trick is simple – start with confidence, keep it clean, and make the room trust you fast.
Most best men make one of two mistakes. They either come in too flat with something lifeless like “For those of you who don’t know me”, or they go too hard too early and throw out a brutal joke that gets more shocked faces than laughs. The sweet spot is somewhere in the middle. You want a strong opener that sounds natural, gets attention, and sets up the rest of the speech without making it feel like a hostage situation.
How to start a best man speech without bombing
A good opening does three jobs. First, it tells the room you are comfortable being up there. Second, it gives the guests a reason to listen. Third, it sets the tone for what is coming next.
That means your first line should sound like you, just a slightly sharper version. If you are naturally dry, go dry. If you are more warm than savage, lean into that. The biggest myth in wedding speeches is that every best man needs to come out swinging with stand-up comedian energy. He does not. He just needs to get the room on side.
The safest formula is this: open with a quick thank you or acknowledgement, follow it with a light joke or observation, then move into who you are and how you know the groom. That structure works because it feels smooth rather than forced.
For example, you might say: “Good evening everyone. Firstly, thanks to the happy couple for trusting me with a microphone and this much potential to ruin the day.” It gets a laugh, shows a bit of personality, and gives you somewhere to go next.
What actually makes a strong opening line
The best opening lines are short, easy to deliver, and built for a mixed room. Remember who is sitting there. This is not just your uni mates on a stag weekend in Prague at 2 am. It is also parents, grandparents, colleagues, and people who do not know your in-jokes. If your opener only works for three lads on table seven, it is not a good opener.
A strong opening usually falls into one of a few types. You can start with a light self-deprecating line, a joke about the pressure of the speech, a warm compliment to the couple with a twist, or a quick observation about the day. These all work because they are broad enough for the whole room.
Self-deprecating humour is often your safest bet. It makes you seem human and avoids putting the groom or bride in the firing line too early. Something like, “I have been told to keep this short. Which is ideal, because most of my best stories about the groom would probably get me removed by security.” That is playful without going nuclear.
Observational openings can work brilliantly too, especially if the wedding has a strong atmosphere. “What a day. The venue looks unreal, the bride looks incredible, and the groom has somehow managed to look respectable for a full six hours.” That gets a laugh and keeps things upbeat.
The opening lines to avoid
Some lines are dead on arrival. Others are risky enough that they are only worth it if you are genuinely brilliant at delivery. Most best men are better off keeping clear.
Avoid anything that starts with an apology. “I’m not very good at public speaking” makes the room nervous before you have even begun. Avoid recycled one-liners people have heard at every wedding since 2009. And definitely avoid jokes about exes, cheating, heavy drinking, arrests, bodily functions, or anything that could make the bride’s family wish they had cut the microphone.
There is also a difference between cheeky and reckless. A stag do story might kill in the pub, but that does not mean it belongs in the speech. If the joke would be a disaster in front of the groom’s nan, bin it.
The room should feel like you are taking them somewhere fun, not making them survive your set.
How to start a best man speech if you are nervous
If public speaking is not your thing, your opening needs to do one very specific job – settle you down fast. That means picking a line you can actually say out loud without sounding like you borrowed it from the internet five minutes ago.
Do not chase the funniest line possible. Chase the line you can deliver cleanly. Shorter is better. Familiar words are better. A steady, simple opener lands harder than a clever line mumbled into your tie.
A good tactic is to memorise only the first 30 seconds word for word. Once you are through that, your breathing settles, the room feels less massive, and you can move into the rest with more rhythm. Practise the opening standing up, not just reading it in your head. Wedding speech panic usually kicks in because something looked fine on a phone screen but sounds awkward when spoken.
Also, pause after your first laugh. Too many best men rush straight through their opener because they are desperate to get it over with. Take the laugh. It makes you look more confident, even if your heart is going full drum and bass.
Examples of how to start a best man speech
Here are a few opening styles that work for different personalities.
If you want safe and funny: “Good evening everyone. I’m [Name], the best man, which sounds impressive until you realise it mainly means I was the groom’s least risky option.”
If you want warm with a joke: “Firstly, what an amazing day. The bride looks stunning, the venue is class, and the groom has done incredibly well for himself – far better than any of us expected.”
If you want dry humour: “For those who don’t know me, I’m [Name]. For those who do, thanks for not warning them.”
If you want a clean nod to the pressure: “I have spent weeks writing this speech. The groom has spent weeks worrying about what I might say. So let’s see which one of us had the better strategy.”
These work because they are simple, punchy, and easy to build from. They are not trying too hard. That is the whole game.
Build a natural bridge into the rest of the speech
Once your opener lands, do not jump randomly into a wild story from ten years ago. You need a bridge. The easiest move is to explain your connection to the groom and set up why your perspective matters.
That might be as straightforward as, “I have known Tom for fifteen years, which is long enough to have seen him at his best, his worst, and, unfortunately for all of us, his frosted-tip phase.” Now you are into the body of the speech without it feeling clunky.
The opening and the next section should feel like one conversation. If your first line is polished but the transition is a mess, the whole thing wobbles. Think of the opener as the front door, not the whole house.
Match the opening to the groom and the wedding
This is where a bit of judgment matters. A black-tie country house wedding needs a different opening from a laid-back city wedding where the crowd has already had a few. Same goes for the groom. If he loves being roasted, you have more room. If he hates attention, a brutal opening will feel off.
Ask yourself one simple question: what version of this speech will the couple actually enjoy hearing back later? Because that is the test. Not whether your loudest mate spits his drink out laughing.
There is always a trade-off. A sharper opening might get a bigger immediate laugh, but a more balanced one usually ages better and keeps the whole room with you. For most best men, that is the smarter play.
A quick word on stag-do humour
There is a reason best men are tempted to open with stag-do chaos. It is familiar territory. The trouble is, wedding speeches are not the stag itself. They are a different event, with different stakes, and a very mixed audience.
You can absolutely hint at the madness. A line like, “After surviving the stag, I feel surprisingly qualified to stand here today,” can work nicely. It gives a nod to the lads without dragging the room into stories better left in Budapest. Keep it suggestive rather than graphic. People laugh more when they can fill in the gaps themselves.
If you are still planning the stag and the speech is looming as well, that is exactly why best men use specialists like Stagmadness – one less thing to wing badly.
The best rule for your first line
If you would be happy hearing your opening played back in front of every guest the next morning, it is probably a solid start. If it relies on shock, private history, or the hope that everyone is too drunk to care, rethink it.
The best man speech does not need a miracle opening. It needs a confident one. Start clean, get the room smiling, and give yourself an easy path into the rest. Once that first laugh lands, you are no longer a bloke clutching a glass and praying for mercy. You are the man steering the room.
And that is exactly where a best man should be.
