Yes, I have. And I knew full well in advance that my buddies Wife had a lot of attractive friends in attendance. I wrote a best man speech that was guaranteed to get the girls laughing their ass off, and it worked. I had lots of people coming up to me after my speech saying it was hilarious. One of them being the woman who is now my girlfriend, whom I've been with a long time. Make a woman laugh, and your desirability factor goes up big time. Weddings are a perfect opportunity to hook up if you make yourself stand out.
