Spank The Monkey.
Spank the Monkey is a game that's really exactly as it sounds - you just spank the heck out of the monkey. "How is that any fun?", you may ask, well, spanking that monkey gives you a score. Each spank is scored based on the speed you spanked it. Still confused? Try it out. It's simple and fun, but is totally addicting. Here's a little secret, you get a bit of fanfare if you go over a certain score.
