Favorite celebrity appearances on The Simpsons

[Sundancer]

No more than 3.


N'Sync -- Can't believe they made the list, but their scene still cracks me up

Stephen Hawking -- classic cameo IMO

Tom Hanks -- his line in the movie about the government using up all its credibility and borrowing his.

 

[O'Haire]

Mel Gibson, James Woods, and Albert Brooks first appearance as Hank Scorpio will forever be my favorites.

 

[Thundercrack85]

Leonard Nimoy. Especially in the X-Files parody episode.
