You may have already seen the hilarious talent that is The Lonely Island. If you watch SNL, then you've seen Andy Samberg who joined the cast this season. And if your sense of humor is anything like mine, you've most likely spewed whatever your Saturday late-night beverage of choice is from your nose due to the writing of his cronies, Jorma Taccone and Akiva "Kiv" Schaffer.
Collectively known as "The Dudes," these guys have been putting together shorts, spoof music videos, and even a pilot for Fox (wasn't picked up) and releasing them online under a Creative Commons license since late 2004.
Their latest creation, The Chronic-WHAT-cles of Narnia, is all over the blogs. I found it through this post on Boing Boing. If you prefer, you can go straight to a flash video of the short available on YouTube (see my earlier post on Online video-sharing services).
