Ahhhh!!
I was best man in my buddies wedding and he was like "You dont really gotta come up with a speech...."
I assumed maybe it was a tiny little wedding where, you know, it didn't really matter.
Oh I was wrong.
So there I was, getting drunk, trying to think something up like an hour before I had to give the speech, all my friends telling me "You're so fucked - how could you NOT write something up!?!?!" (I HATE talking in front of crowds.)
Didn't throw any jokes, just kept it short and sweet and talked about how I knew the dude since first grade, blah blah, good luck to the new couple, etc, cheers!
Have fun! Weddings are fucking awesome....I always end up wayyyy too drunk.
