There are devices used in some radio specialties known as duplexers, diplexers, triplexers. These are, of course, not identical. Often they look like weird cans with some odd attachments.

And there is a term used for a particular sort of body-slam in professional (show) wrestling.

Combine them and this nonsense happens:

First Panel:
Guy at radio/parts shop looking over various items.
"Diplexer, Duplexer, Suplexer, Triplexer. ... Suplexer? What's that do?"

Second panel:
Guy flat on his back, obviously JUST slammed there (*OOF!*)
"Alright, don't need one of those in the shack."
