"There's a difference between a caper and a prank. A prank is like playing Ding-Dong-Ditch, you know, you ring the doorbell and then run and hide in the ditch. That's a prank. It has no shelf life, like reassembling the principal's car up on the roof of the gym. It's cute and everything but there's no shelf-life, and it can actually be kind of destructive. But a caper is different. It's something where everybody has made it in."
