Need to procrastinate? Famousr is your answer!
There’s three modes. The first (default) mode is to guess which of two given celebrities is ‘more famous’. The definition of ‘more famous’ is based on the user’s rankings – so obviously if you’re incorrect today it doesn’t necessarily mean that you’ll be incorrect in a month’s time. The second mode allows you to put in the name of two actors and the site will tell you who is more famous (apparently Mary-Kate is more famous than Ashley Olsen). The last is my favourite – Who’s “That Guy”? shows you a grab of an actor (usually not very famous) and a list of movies and you have to pick which was their biggest one.

Great site to waste some time on.
