The Nutty Professor (1963)

Continuity mistake: In the beginning, Jerry Lewis makes his special drink and it is the consistency of a milk-shake. Later in the movie he makes the same drink and it looks like cloudy water.

Dr. Hamius R. Warfield: Kelp, it's human nature. Kelp, people just don't like teachers blowing up their kids.

Trivia: While the principal of the school is going through the list of everyone performing at the prom, he mentions a comedy duo, and says "Oh, I thought they split up." A wry reference to the earlier break up of Martin & Lewis.
