Cheech and Chong are named for the first name (“Cheech” [aka Richard] Marin) of one player and the last name (Chong - Tommy Chong) of the other. Penn & Teller are similarly named: Penn Jillette and Raymond Teller. *
What (if indeed there are any) are some other acts that are similarly-named?
*Yes, I know Raymond Teller performs mononymously under the name “Teller”; please work with me here.
You could include O.C. and Stiggs if you’re willing to go with characters rather than performers. The characters were Oliver Cromwell Ogleby and Mark Stiggs. (For those not into eighties trivia, O.C. and Stiggs were from a series of short stories which were made into a not very successful movie.)
In the National Lampoon stories, “O.C.” stood for “Out of Control.” The “Oliver Cromwell” thing was an innovation of the film. A British comic book took the basic premise and gave it an alien setting: “D.R. and Quinch.” “D.R.” stood for “Diminished Responsibility.”
Vaguely recalling an old TV show starring Pat Morita: Mr. T and Tina.
