Haha! I've played "I never" waaaaay too many times! It *always* ends up pretty vulgar. The most vulgar probably (and this is going to sound like the "easily offended don't click here" thread) is when someone said "I've never had butt sex" and some people drank and it became a drunken debate over anal sex. Then there was "I've never kissed someone of the same gender" and all the women drank except my friend Cate. I said, "Oh, sweetie, I'll kiss you!" and did!
I'm much, much better at getting myself to drink than getting everyone else to drink.
