I've never had to get up and take a piss during a film. Not even ____ like LOTR. I'm too interested in what's going on during the film to feel my bladder. It's never been an issue.
I do remember when the first Spider-Man came out in 2002 I drank this big ____ing soda. I'm not much of a soda drinker now, at the movies I don't get anything, not even popcorn, but in 2002 it was different. After the film I had to piss like a race horse. I go to the bathroom and was in there for like, man, 5 minutes continuously. No joke. Probably the longest I ever had to piss. I thought there was something wrong because I couldn't stop.
