Best Man Speech

Best Man Speech I’m the best man at my buddy’s upcoming wedding, and I’ve decided to go ahead with doing the traditional best man speech. Looking for any advice you all may have to offer! I’ve got a relatively mild block, which as we all know tends to worsen drastically when speaking publicly or under pressure. I’m thinking of beginning with a little self deprecating joke at the start of it to let everyone know that I’m comfortable with it and then we can move on to the substance of the speech. Do you all have any advice for a light joke of that nature, or broader advice for this kind of speech?
