Stooge Physics would make a great college course.
I can imagine it being a great draw. Administering the laboratory could be a bit tricky, though. You would have to have the students sign a release form.
Don't forget about the horseshoe that was placed on top of a doorway, hanging by a nail, that would fall on one's head only to bounce straight back into place above said door. (Love At First Bite)
OR when a pineapple is being thrown at a person down the hallway and the thrown pineapple seems to hover through the air, in wavy up-and-down fashion, towards the person at which said fruit is thrown. (Pardon My Scotch)
Ah, you mean the pineapple that flies around the corner and hits its target off-screen! That is one of my favorite ballistic improbabilities on screen, along with the bit in The Simpsons
("Homer the Clown," season 6) in which Homer, employed as a stand-in for Krusty the Klown, crashes his car into a tree, sits motionless in the cab for a second or two, and then suddenly is flung through the windshield (without serious injury, of course).
