Bill Cosby = Fat Albert

See, I'm not so bad with the voices myself! Okay, so that's the only one I really know.

As for Itchy and Scratchy, there was an episode where they tried to ad a third charactor and Homer met the voice of itchy and scratchy. Mick, is the charactor in that episode the same (or based on) the person who really does their voices? As for Side Show Bob, I know Phil Hartman did a lot of classic Simpsons charactors (like Linol Hutts and more). If I had to guess, Phil would be my answer. Would I be right Mick? I do love the Simpsons I must say.
