World of Warcraft Easter Egg - Loony Toons

If you get the achievment "Shop Smart Shop Pet...Smart." you will recive a in-game companion skunk named Stinker. If you come across any cats while Stinker is out, he will chase after them with a heart above his head, and then will come back to you when the heart breaks. This is supposed to be Pepe Le Pew from Loony Toons who is in love with a cat and chases her around, thinking she is a skunk.
