TBS is running a short quiz-like website, that will help determine what everyone finds funny. You get to watch a guy getting balls thrown at his body parts, some funny and some not so much. There is music and sound at this website, so turn down your speakers before going to it.
It's fun enough and pretty short, and you can do it as much as you would like. It's not earth shattering entertaining, but if you are bored... or avoiding work, it'll take ten or fifteen minutes out of your life.
