"Kwyjibo on the loose!"

Quote of the Week:

Bart:  Here we go.  Kwyjibo.  [places his tiles]  K-W-Y-J-I-B-O. Twenty-two points, plus triple-word-score, plus fifty points for using all my letters.  Game's over.  I'm outta here. [gets up]
Homer: [grabs Bart with his left hand, holding a banana in his right]  Wait a minute, you little cheater! You're not going anywhere until you tell me what a kwyjibo is.
Bart:  Kwyjibo.  Uh... a big, dumb, balding North American ape.  With no chin.
Marge: And a short temper.
Homer: I'll show you a big, dumb, balding ape!  [leaps for Bart]
Bart:  [making his escape]  Uh oh.  Kwyjibo on the loose!
