Simpsons / Muppets

[uncleduke]

There was a lot of talk a few weeks ago about the similarities between the Muppets and the Simpsons on one of the other boards. It got me wondering tonight, What Muppet guest stars also appeared on the Simpsons. I came up with Linda Ronstadt and Steve Martin.
Anybody else think of any?

Michelle Pfeiffer and John Goodman were both on "Muppets Tonight" and were both also guest voices on "The Simpsons"....I'm SURE there are more than just these four...
