Ah, the best man's toast. They can be absolutely lovely -- so moving that there's not a dry eye in the house. They can also be excruciating to sit through, especially if the best man has had one too many glasses of champagne punch. If you're worried that your man's best man will give a toast that falls into the latter camp, pass this best man's toast how-to onto him.
First off, the most beautiful sentiment you can express is the positive change you've seen in the couple since they met. If you're having trouble coming up with the right words, ask yourself how the groom has grown and evolved since meeting his future wife. How has he changed overall since you first met him? If you were kids together, choose an anecdote from your youth to share.
When you think about adding humor, remember that everyone has a different idea about what's funny and what isn't. Keep in mind that you are speaking to a wide demographic and some people will take what you say very seriously. It's best to always remain proper and gracious. Don't share any embarrassing stories or talk about sex.
But be yourself. Don't look for a very formal script from a book if you aren't a formal person. Make sure your toast sounds like you. There are lots of ways to personalize your toast to keep the audience engaged.
Above all, remember to keep your toast very, very short. When you're done toasting, thank the audience for coming even though you aren't the host. Being the best man, you had a vested interest in your good friend's wedding turning out perfectly, so you're well within your rights to do so.
(By the way, if the maid-of-honor is giving a toast, these guidelines will apply to her as well!)
