Always hated having to stand there while it happened, so no way was I doing it at my own wedding! Hate the garter, too. I'm always so embarassed for the couple, the parents, everyong when the husband's head goes under the dress!
My friend did the anniversary dance at her wedding last week. It was nice, but people didn't understand how to do it right and the dj was no help, so it was sorta dumb.
I figured, in the time it takes for bouquets and garters I can dance to least one actually fun song, so I didn't do them.
