I'm going to go ahead and add Homestarrunner.com's Decemberween specials. I'm watching some of them now, and they are hillarious.
Here are some of my favorites:
Teen Gril Squad Decemberween episode- In this one, the girls are having a secret Decemberween gift exchange. Trouble is, instead of drawing names out of a hat, they draw names out of the mouth of a canivorous lion...
sbe-mail- What I Want- Strongbad gives a list of the things he doesn't want for Decemberween. A christmas orniment ("what better gift to give than something that becomes useless for a year after you unwrap it"), a singing dancing Christmas robot, anything homemade, and homemade orniments (which he dubs a no-gift for being 2 things on his wish not list)
Sweet Cuppin' Cakes: Cactus Coffee and the No Tell Motel- If anyone is familiar with the sbe-mail "crazy cartoon" you'll know why I like it.... from the words of Homestar himself "What's not to understand? Eh! Steve!'s mouth exploded the universe, and that blond guy did a tiny, tiny dance. "
Decemberween Short Shorts- A Peanuts Christmas Tales-esque collection of weird cartoons about Decemberween. First up, Strongbad writes a letter to tube socks. Then the gang is talking orniments on a tree. Strongsad is the "most expensive orniment on the tree by about 40 bucks." and is be-dazzled off the tree by Strongbad's 59 cents worth of styrofoam and cheap plastic sequins. Now we see a old time Homestarrunner cartoon in which an alien admires old Time Homestar's Decemberween rat pile ("it's the most sanitary day of the year."). And Finally, Homestar sings a song to cheer up Coach Z.
