So, you’re going to see “Transformers 2” and you know you’re not going to make it through the entire movie because it’s 2 1/2 hours long and you’ll be drinking a mega soda that they call a small. But you don’t want to miss the good part. Don’t despair, take out your IPhone and the handy RunPee app will let you know when you can go to the bathroom and it even lets you know what happened while you were gone. And it’s only $0.99! How cool is that?
