Julie Kavner does marge.

nancy cartwright does bart.

I have seen it and its still funny. I wonder who does the Marge and Bart voices?

i think it wood be cool to meet them, you have a conversation with mr burns, that wood be weird. they got the characters personalities down too in that spontaneous bit.

Awesome. It's amazing they can do such a range of characters voices.

I love it.
Krusty's voice always manages to crack me up :]

The way they effortlessly shift between characters is a real treat to watch.  Of course, it helps that the characters they're doing are from my favorite show of all time.

Haha. Excellent. As Shark said, Homer sounds a bit off, but the rest are spot on. It's incredible seeing these two men doing what they do best.

So priceless.  It's so odd to see so many multiple unique voices coming from two guys, especially when they're already attached to characters you know and love.

omg those guys are so hilarious, and damn quick too. homer sounds a little different maybe cos its on a chat show... i love Dr. hibert though :p
