While playing Scrabble, Doogie comments that Vinnie played SCREWED on a triple word score. While the word does appear on the board as shown, it is played in the middle of board, nowhere near the eight triple word score spots around the edge of the board.
Doogie's Journal Entry: November 22, 1990... Thanksgiving. Had turkey and pumpkin pie. Grandpa ate crow. Dad sampled the fruits of victory. Vinnie tasted sweet satisfaction. I hope the leftovers last all year.
The German episode title is "Das schwarze Schaf", meaning "The Black Sheep".
