Let me just say, the internet makes tracking down these kinds of things next to impossible. I have to scour foreign video sharing sites, struggling to ascertain which Russian or Chinese characters translate to "embed". I could never let you down in my quest to bring you a classic Christmas episode, though; I'd navigate hundreds of bootleg Chinese video sites just to bring you a little bit of no-copyright-intended holiday cheer.
This particular episode certainly isn't for everybody. It's rude, it's crude, it's downright ridiculous. Alright, that seems like fair warning to the easily offended. Enjoy!
