... And that's when RunPee.com comes in handy. The Website, which has been featured on NYTimes.com, lists movies currently in theaters, and offers handy suggestions for exactly when during the movies' run times you can slip out to the bathroom or the concession stand without missing anything important. And if you want to know exactly what you'll miss, RunPee provides a summary, which is scrambled in case you don't want the spoiler.

Is this the best idea ever?! Actually, the site is only accessible via the Web for now, but the site promises it's "coming soon to an iPhone near you," which will absolutely make it one of the best, most helpful, ideas ever.
