"That's much too vulgar display of power, Karras!"
A famous line from "The Exorcist" (1973), despite its dubious use of grammar. Spoken by Satan during his possession of Regan, as a refusal to prove his power by such unsubtle means as making things fly about a room. Strangely, he spends most of the film doing just that.
It is also generally considered the best album by heavy metal quartet Pantera, released in 1992, and presumably named in honour of the above.

Incidentally, I once devised this contrived joke:
Q. What do you call it when Phil Anselmo shows you a tall building while swearing?
A. Vulgar Display of Tower!
It took me hours to think up.
