The great equalizer.

There is one thing irresistable to all people. Young and old, rich and poor, stupid and not stupid. Animal Fights! The only thing more compelling than blood lust is adorability. So when you see a kitten take on a turn table, or a squirrel and a couple of birds fight over a nut. You can be the hardest mofo on the planet, but it'll get ya... it'll get ya.

I found http://www.maniacworld.com/Animal_Fights.htm by accident and I haven't been able to get shit done since. Beware it eats up all of your time. The cuteness in that page destroys lives.
