Appearing in only one episode out of hundreds, these characters quickly became a part of Simpsons history.

A few notes on this list: In order to be considered, a character can only have appeared in one episode. The only exception is characters who later appeared in nonspeaking background roles. Also, the characters represented are from the first eight seasons only. Sorry, fans of later-season Simpsons.

Each character was memorable. Frank Grimes didn't deserve to die. That episode pushed Homers' stupidity to the fullest. I enjoyed the episodes with Barts' girlfriends and Lisa with the crush on her teacher was enjoyable. Great characters from classic Simpsons.

Yes!! They mentioned Shary Bobbins - definitely one of the most memorable characters ever on the show. I also loved the Jessica Lovejoy episode. :lol:

Since, I'm a huge fan of his, the Larry Burns episode tops it for me. Love Rodney Dangerfield. The scene I liked is when Homer and Larry are in the house and Marge insists they turn themselves in and when there leaving the house, Homer screams because he notices the tv cameras. Just classic.
