"If you shoot a mime, should you use a silencer?” is a jocular one-liner that American stand-up comedian Steven Wright used in his act since at least 1986. “Do you need a silencer if you are going to shoot a mime?” is the form that the saying took by at least 1993, when it was included with similar questions in a much-reprinted grouping titled “Why Ask Why.”


Wikipedia: Steven Wright
Steven Alexander Wright (born December 6, 1955) is an American stand-up comedian, actor, writer, and Oscar-winning film producer. He is known for his distinctly lethargic voice and slow, deadpan delivery of ironic, philosophical and sometimes nonsense jokes, paraprosdokians, non sequiturs, anti-humor, and one-liners with contrived situations.

23 May 1986, The Daily Northwestern (Evanston, IL), “Laugh-in: Wright pleases Cahn crowd despite interference” by Laura Goldberg, pg. 3, col. 2:
He (Steven Wright—ed.) continued firing off one-liners and questions such as, “If you shoot a mime, should you use a silencer?” and “My school colors were clear.”

6 December 1987, Sunday News Journal (Wilmington, DE), “On the tube,” pg. K8, col. 4:
“If you shoot a mime, should you use a silencer?”
