What are some websites that I can go on just to waste a few hours (similar to Tumblr, Buzzfeed, Youtube, or Polyvore)?

I enjoy Cracked.  I also enjoy reading the comment section on Politico.  The level is discourse is very low.  It is funny to read people basically calling other people "poopy head" and similar.

You might enjoy Badgers. 

And for any English contributors, here's one about the badgers playing football for England. Footy. It's a goal!
