General Humor (not sketches but still funny)

Planet Boredom
http://www.planetboredom.net
Planet Boredom features a large library of articles, images, and videos. They've also got a great forum community.
Break (formally big boys)
http://www.break.com
Break (formally Big Boys) is pretty much videos of people getting hurt; its hilarious.
Kontra Band
http://www.kontraband.com
Kontra Band is your typical website, but it earns major points for being ninja themed.
Ebaums World
http://www.ebaumsworld.com
Ebaum has been taking some flak in the flash developer community lately, but I still think that the "eLinks" section is worth looking at.
Weebles Stuff
http://www.weebls-stuff.com
Weebls Stuff is focused on flash content. I recommend the badgers cartoons, and banana/salad fingers.
College Humor
http://www.collegehumor.com
I dont see how the humor is exclusive to college kids, infact, besides the articles about roommates, its pretty much the same as these other sites.
