Hit animation The Simpsons is best known for its dysfunctional family Homer, Marge, Bart, Lisa and Maggie, but it isn't just these five that make the show as popular as it is today. Literally hundreds of other characters make up the comedy, from school teachers, bar dwellers, schoolyard bullies and even mob bosses and attempted serial killers. Voice actors Dan Castellaneta, Julie Kavner, Nancy Cartwright, Yeardley Smith, Hank Azaria and Harry Shearer lend words to most of these, but Springfield has also been frequently blessed by celebrity guest appearances throughout its two-decade-long run.
