Jon Vitti

Jon Vitti is a writer who is most noted for his well-received scripts for the television series The Simpsons. He has also written for the King of the Hill and The Critic series, and has served as a consultant for several animated movies, including Ice Age (2002) and Robots (2005). He is one of 11 writers who worked on The Simpsons Movie.

He most recently co-wrote the live-Action/CGI animated adaptations of Alvin and the Chipmunks: ' (2007) and ' (2009).

He is a graduate of Harvard University, where he contributed to the Harvard Lampoon. Prior to joining the Simpsons show, he had a brief stint with Saturday Night Live. He has stated on a DVD commentary that it was "a very unhappy year".

He is sometimes credited as "John Vitti".

He has also used the pseudonym Penny Wise. Vitti used the pseudonym for episodes "Another Simpsons Clip Show" and "The Simpsons 138th Episode Spectacular" because he did not want to be credited for writing a clip show as expressed on Simpsons DVD commentaries yet ironcially his name was credited for writing the first Simpsons clip show "So It's Come to This: A Simpsons Clip Show". The director of "The Simpsons 138th Episode Spectacular", "Pound Foolish", has been revealed to be David Silverman.
