It's a happy birthday to Isla Fisher, who turns 31 today. Isla, you were a hoot in Wedding Crashers — even if you did use a body double and a hand double. In ways both broad and subtle, you captured what it is guys like about crazy chicks, even when we know they're crazy. And in honor of fiancé Sacha Baron Cohen (one can only imagine the crazily play-acted circus sex) I'll even include another linked picture.
