Two math professors are in a restaurant. One argues that the average person does not know any math beyond high school.
The other argues that the average person knows some more advanced math. Just then, the first one gets up to use the rest room.
The second professor calls over his waitress and says, “When you bring our food, I’m going to ask you a mathematical question. I want you to answer, ‘One third x cubed.’ Can you do that?”
The waitress says, “I don’t know if I can remember that. One thurr… um…”
“One third x cubed,” says the prof.
“One thir dex cue?,” asks the waitress.
“One”
“One”
“Third”
“Third”
“X”
“X”
“Cubed”
“Cubed”
“One third X cubed”
“One third X cubed”
The waitress leaves, and the other professor comes back.
