Ever been bouncing in your seat in a movie theater because you drank too much of that over sized Sprite... trying to guess when is the best time to make a bathroom break for it. Well there's a website for that.... Runpee.com lists current movies and suggests the best time during the movie to "run pee." It gives you several times per movie, says how many minutes in and gives a line of dialogue at that point so you'll know when to go. Tells how long long you have before something good happens & even has a paragraph of scrambled text that you can click to decode and see what you've missed while you were away.
They also tell you which films have scenes after the credits.
