How do I know what humor is appropriate in the best man speech?
I’m so glad you asked this question. Many best man speeches have been spoiled by poor judgment in this arena. The answer to this is subjective, but keep this in mind; there will likely be children present, and there will be people of all ages adulthood listening to the best man speech. You want them all to be able to relate to and laugh at your humor.
Poking some fun at the groom is expected in typical best man speeches, but I would avoid poking fun at the bride in the best man speech. Never mention ex girlfriends in the best man speech, and don’t insult anybody even if they are not a guest at the wedding reception.
