Writer's Block: Doh!
Ralph Wiggum or Marge or Mr. Burns.
Ralph is great for the LOLS. I always laugh at his one liners. My favourite one would have to be:
Ralph (To a wolf): Will you be my mommy? You smell like dead bunnies...
Or
Ralph: When I grow up I'm going to Bovine University.
Marge because she tries so hard. And because Homer can't say her maiden name and is a bit of a dolt but she still loves him. (:
Mr. Burns because he is a classic...hands down is very, very amusing.
Mr.Burns: Quick Smithers. Bring the mind eraser device!
Smithers:You mean the revolver, sir?
Mr.Burns: Precisely.
Mr.Burns: Ketchup...Catsup...Ketchup...Catsup.
EDIT: I FORGOT GRANPA SIMPSON! He is hilarious. LOL
Grandpa: One way to get rid of them is to tell 'em stories that dont go anywhere.
