It's been on for more than two decades, but the Simpsons are still as funny as ever. Not only are they a hit on Fox, but also in syndication, DVD and on the big screen.
We all know the Homer, Marge, Bart, Lisa and Maggie, but what about the secondary characters? Who are the best? Is it Sideshow Bob or Krusty the Clown? Maybe Grandpa Simpson or even Apu?
