45. The Best Man
At my wedding. A friend got hammered early and overtook the microphone during the best man/maid of honor speeches. He brought up all his friends (wife knows him better) to make speeches even though they has nothing planned. My wedding DVD now has about 30 minutes of cringeworthy, uncomfortable speeches thanks to him.
Later that night he stole a bottle of JD from the bartender and hid it under a table before he passed out.
