Woman to guy, about guys making moves on drunk girls they are friends with: So, why do you guys do something like that? It never works.
Guy: Sure, 9 times out of 10 it doesn't work, but that one time you score.
Woman: But aren't those other 9 times really awkward and damaging to your friendship?
Man: Yeah, but there's that one time where you get sex you really weren't expecting!
