Context

This line is spoken by Igor, played by Marty Feldman, and then repeated back by Dr. Frederick Frankenstein, played by Gene Wilder, in the classic comedy Young Frankenstein (directed by Mel Brooks, 1974). 

Igor is Dr. Frankenstein's sidekick. The Robin to his Batman, the James Franco to his Seth Rogen. When Dr. Frankenstein wishes he had a brain for his fresh new monster, Igor goes to get one. After dropping the good brain, he grabs one labeled "abnormal."

Predictably, Frankenstein's monster goes berserk, and the doctor wants to know why. When he interrogates Igor about the brain he found, Igor says it belonged to "Abby… someone." But Abby who? Abbie Hoffman? Abby Cadabby? Abby Lee Miller? (That would explain the monster's passion for dancing.)

But no. Igor confesses the brain came from "Abby… normal." Abnormal. Uh-oh.

Where you've heard it

Igor actor Marty Feldman, whose eyes were on loan from Jim Henson's Muppet Workshop, is a comic legend.

Pretentious Factor

If you were to drop this quote at a dinner party, would you get an in-unison "awww" or would everyone roll their eyes and never invite you back? Here it is, on a scale of 1-10.

You don't need a normal brain to see that this is a pretty un-pretentious quote.
