Mine didn't require much thought. I thought I'd choose something that represented my interests, rather than myself, yet wouldn't mean much to someone not "in the know". For those of you who are not fans of The Simpsons, I provide the following definition:
kwyjibo (n) - A fat, dumb, balding, North American ape with no chin.
Taken from the episode "Bart the Genius", kwyjibo was the word that enabled Bart to win the Simpson family's Scrabble game. Bart came up with that definition while being pressured by Homer. For more details, I suggest you purchase The Simpsons Season 1 DVD.
LOL!!
D'oh!
