I've only recently discovered the blog Yankee Pot Roast, which bills itself as "The Journal of Literary Satire, Hastily Written and Sloppily Edited." It's a wild assortment of various humor columns, lists, post, and stories. Great stuff! Here are a few good examples:
A Six-Year Old with a Future in Elected Politics Tackles a Tough Question
"Yo' Momma" Jokes as Told by Nerds
Recipe for Disaster
William Carlos Williams is a Really Bad Roommate (which I recently linked to).
