Piss before going up there. Keep the tone of the speech light and congratulatory. Also, I wouldn't write it down; just kinda remember key points you want to mention. And smile! Most important thing

no, the most important thing would be not to insult the bride

Mr. Le Chiffre: No, I believe in a reasonable rate of return. James Bond: Now the whole world will know you died while you were scratching my balls!
Just talk about how happy you are for him, what a good brother he is, and how he would make a good husband and father, or something like that.
Be natural.
Smile, stand up / walk up to the mic or whatever, and greet the audience. Perhaps start off with a "Hello, most of you know who I am, but I'll introduce myself again in case some of you have forgotten me,"
Be honest, and speak clearly. That's what makes a good speech. Make it interesting, and don't go on and on about similar points, but make it short and catchy, ya know?
If you get too nervous, remember that you can do this, it's just a matter of getting over your fear of embarassment, etc. Drink a glass of warm water, stay calm and watch how you pronounce your words, body language and try making some eye contact with the audience.
I've done a bestman speech before...for my oldest brother. I opened with an anecdote from the past, you know for emotional pull, then I made fun of him a little, then congratulated him, then left with a joke that blasted all of my family. It worked.

Pretend as though you are the Commander of a Roman army who is about to do battle with the Barbarians and the wedding guests are your soldiers. There is a very good chance that you are all going to die within a few moments so, your speech is the least of your concerns.
Use this for inspiration. This movie helps me get through the day.
Seriously though, you should either take the stage dressed as a Roman commander or a Ghostbuster. IF you dress as a Roman Commander tell the people that you would never go into battle without your best mate. If you dress as ghostbuster, tell the people that you wouldn't bust your friend if he turned into a ghost...,thats just how good of a man he is.
your welcome.
