Favorite Joke channel: 一天一囧 on tudou.com

This is a great joke channel for Chinese jokes on tudou.com (tudou is like a youtube.com for China). 
一天一囧

If you don' t know what 囧 Jiong means, you can check it here on italki answers.

There's also a great site called chinasmack with an awesome glossary

Anyway, it's a sort of silly site, but it's sometimes pretty funny.  (Your Chinese has to be pretty good to get it...)
