Room 222 - Season 5 Episode 12 MPG
Overview: The Walt Whitman auto shop enters a car in a contest to see which vehicle gets the most miles per gallon. The actual race is unbearably slow, with each car conserving energy, and the scenes of Mr. Kaufman, Mr. Dixon, et al, trying to stay awake in the bleachers are hilarious. Thanks to Oriole Adams for suppyling this synopsis.
