See now I really liked Tommy Boy but not the dumb and dumber or black sheep movies
I LOVED Tommy Boy! I saw it twice...favorite scenes:
1.) Tommy Boy smashing his head on the girder while examining the hardhat in his hands, trying to figure out what to do with it...
2.) Tommy Boy eating the Peanut M&M's in the cherry car while David Spade tells him no eating allowed. He blows him off and puts down the bag of M&M's on the dash, and when the brakes are applied, they spill out of the bag and all disappear down the heating vent.
3.) The evil guy trying to shoot his gun, and getting screwed by the 80's era automatic seat belt...
