There's really no rational reason why I just played PapiJump [App Store] twenty times in a row at 2 a.m. It's a stupid game with a stupid name... or so I thought.

The game is deceptively simple, but surprisingly addictive, especially once you start submitting your high scores. My 20 game run was actually an unsuccessful attempt to unseat Chris at 47,024, but I only made it to 11,641 (see attached image). Tip: if you go off of one side of the screen, it wraps around.
