Just keep drinking, Jen -- that bouquet is mine.
Because who doesn't want to drink out of a bottle that fifty other people's lips have touched, this is a video from a GoPro attached to a bottle of Fireball (sweet, cinnamon flavored candy liquor designed for children) being passed around a wedding. Surprisingly, there wasn't a single guy who pretended to whip his peenor out and pee in the bottle like any normal person would have done.
Keep going for the video.
Thanks to Cathy M, who tried doing the same thing with a bottle of gin but nobody was into it. Probably because gin is disgusting unless you really, really hate yourself, in which case it's the only medicine for your sickness.
