Saw Goblet of Fire the other day, personally think it is the best HP film so far, was not bored once during the whole thing, and believe me I was bored during the previous films.

...

I love my guy-friends, I really do, they tell me things about the male body that I'd otherwise never find out anywhere else. Apparently, it is quite easy for a man to sit on his own penis (balls). In all honesty, I could not stop laughing for several moments after that bombshell. Love the guy-friends.

ETA: Included balls, because I realised that they were never too clear about the subject.
