Dan Florio couldn't recall ever getting up to use the restroom in the middle of a movie, but he was tempted when he went to see the remake of King Kong.

"By the end," Florio says, "I was hoping they would just kill that ape." Then, as he walked out of the theater past the queue for the next showing, something else occurred to him: how great it would be to tell them which scene provided the best chance for a bathroom break.

While Florio wasn't gregarious enough to engage the crowd--one can only imagine the reaction--he quickly realized that this was an opportunity to use his skills as a web developer and have some fun, too. Soon, RunPee.com was born.
