Funny Best Man Speech Openers That Actually Work

The short version: the funniest opening line for a best man speech is a specific, affectionate detail about the groom, not a joke about speeches, weddings, or being nervous. Say who you are, then say the detail. Six opener shapes that work are below, with more than twenty fill-in-the-blank lines, plus the openers to retire and a way to test yours. For the full structure of the speech after the opener, see the best man speech guide.

The reason most best man openers fall flat is that they are about the wrong thing. "For those who don't know me" jokes are about the speaker. "Webster's defines marriage" jokes are about marriage. "I was told to keep this short" jokes are about speeches. None of them are about the groom, and the room came for the groom. The instant you say something that could only be true of him, people lean in. The instant you say something that could be said at any wedding, they go back to their plates.

The rule

Every good opener does two things in the first twenty seconds: it says who you are, and it says something only true of the groom. Everything below is a way of doing the second part.

The other rule: the laugh has to land somewhere kind. A roast line with a turn ("he is the most stubborn person I know, which is why I'm not surprised he spent three years convincing Elena to give him a second date") is a compliment wearing a joke. A roast line with no turn is just an insult at a wedding. Every opener here is built with the turn in.

Six opener shapes that work

1. The intro with a twist

Your name, your connection, and one small surprising detail about how the friendship works.

• "I'm Dan. Marcus and I met in seventh grade when we were assigned lockers next to each other, and I have been standing slightly to his left ever since."
• "I'm Owen, the older brother, which means I've known Theo for exactly his entire life. I'd say that gives me a lot of material, but most of it is stories about me being awful to him, and I've decided tonight isn't the night."
• "I'm Chris, and Jamie and I have worked together for nine years, which means I've spent more waking hours with him than his wife has. She's about to fix that."

2. The affectionate stat

One absurdly specific number about the groom. These work because they are clearly true and clearly loving.

• "Marcus owns four identical grey hoodies and will defend each of them individually."
• "In the twenty years I've known Theo, he has been on time to exactly one thing, and we're all sitting in it."
• "Jamie has texted me 'you up?' at two in the morning more than four hundred times, and not once has it been about anything interesting."
• "Sam has never finished a book, a podcast, or a series, and yet he has somehow finished a proposal, which I think tells you what he thinks of Priya."

3. The self-deprecating open

Make yourself the target first. It buys goodwill for everything you say about him later.

• "Marcus asked me to be his best man, which either says a lot about how much he trusts me or a lot about how few other friends he has. I've chosen not to ask."
• "I want to say up front that I'm not a public speaker. Jamie knows this. He asked me anyway, and I want the record to show that this was his decision."
• "Theo told me to keep this short, classy, and not too much. So I'd like to apologize to Theo, because I only heard 'short.'"
• "I've been told the best man speech should be about the groom, so I'm going to try very hard not to make it about the fact that I'm single and this is an open bar."

4. The prediction that came true

Something the groom said years ago, or something you said about him, that today proves right.

• "When we were nineteen, Marcus told me he was going to marry someone who 'actually gets it.' I said that person didn't exist. Elena, I'd like to formally retract that."
• "Ten years ago I bet Theo twenty dollars he would never leave a party before midnight. I've been watching him leave parties before midnight for three years now, and I still haven't been paid."
• "In college, Sam wrote a list of what he wanted in a partner. It was mostly about pizza. He's done better than the list, and I'm relieved for everyone."

5. The first time you heard about the partner

How he talked about them, and what was different.

• "I knew something was different because Jamie, who once described a three-week trip to Japan as 'fine,' spent forty minutes telling me about a woman he'd had one coffee with."
• "Marcus doesn't usually talk about people. He talks about what they said. And for about six months, every conversation had an 'Elena said' in it somewhere."
• "The first time Theo mentioned Sam, he said, 'She's very calm. It's weird.' That was four years ago. She's still calm. It's still weird. He's still here."

6. The thing he is famously bad at

The trait everyone in the room knows, turned into the reason he's a good partner.

• "Marcus cannot cook. He can, however, drive forty minutes to get the exact thing Elena actually wanted, which I've come to understand is the more important skill."
• "Theo has no sense of direction. He has never once found a restaurant on the first try. He did, however, find Sam, so I think we can call the navigation problem solved where it matters."
• "Jamie is the worst texter I have ever met. Days of silence, then a single 'yeah.' The one exception, for four years now, is a woman named Alex, who gets full paragraphs. Some of them have punctuation."

Openers to retire

The room has heard every one of these. Some of them will also make the bride's grandmother go quiet.

• "For those who don't know me, I'm the better-looking one." Every wedding, every year.
• "Webster's dictionary defines marriage as..." It was not funny the first time.
• "I was told to keep this short, so..." Fine as a self-deprecating beat (see shape 3). Deadly as the whole joke.
• "Marriage is a three-ring circus: engagement ring, wedding ring, suffering." No.
• "Ball and chain," "the old ball and chain," "his freedom ends today." These frame the bride as a punishment. Her family is sitting right there.
• "He's punching above his weight." Meant as a compliment to her. Lands as an insult to him, at his wedding, with a comparison built in.
• Anything about the bachelor party. Whatever happened is either boring to the room or unfit for it.
• Anything about an ex. No context makes this work.
• "I've never done this before, so bear with me." Every nervous speaker says it, and it only lowers expectations. Your material is good. Start with it.
• A joke you found by searching "best man jokes." If it came up for you, it came up for the last three best men this room has heard.

How to test an opener before the wedding

1. Read it out loud, standing up. A line that reads well on a phone often dies out loud. If you stumble on it three times, it is too long.
2. Read it to one person who knows the groom but is not in the wedding party. A laugh means keep it. A polite smile means cut it. "What does that mean?" means it is an inside joke, and the room will not get it either.
3. Ask whether his mother would laugh. Not tolerate. Laugh. If you are not sure, it is a no.
4. Ask whether it could be said at any other wedding. If yes, it is a joke about weddings, not about him. Replace the generic part with a detail.
5. Count the words after the laugh. If you need a sentence of explanation after the punchline, the punchline is not working.

What comes after the opener

An opener buys you the room's attention for about ninety seconds. Spend it on one story, told with detail, that ends with the groom looking good. Then the turn, where you show what changed when his partner came along. Then speak to the partner directly. Then the toast. The best man speech guide walks through each of those with three complete speeches, and how long a wedding speech should be covers the timing.

Two or three laughs across the whole four minutes is the target. The opener is one of them. Do not spend the rest of the speech trying to top it. Spend it being honest about your friend, and the room will remember the whole thing as funny.
