MAD Magazine - the Cartoon - spoofs Clone Wars
Also spoofs Transformers in a fairly funny episode that I felt was much more in the MAD Magazine vein than Mad TV was. This was their second episode, and the 11-minute format I think suits it.
The Groan Wars segment's opening text cracked me right up, some of those opening texts have gotten pretty dopey on CW and they nailed it. The stuff about the art style reminded me of Chuxter's comments. :p Ahsoka was a bit funnier a concept than I had expected, though they went toothless on attacking her character, sticking to the easier realm of her looks.
Anyway, the full episode is currently online. For how long? I dunno, so watch it while you can:
