Politician's Backroom Deal

Okay, listener, you're not the sharpest crayon in the box, but Explain bear is here for ya! This joke is a pun, see? You probably know what "anal sex" is, you degenerate. And a "backroom deal" is when politicians make secret agreements, often unethical ones, behind closed doors. The humor comes from the double meaning. "Anal sex" involves the "backroom" (the anus), and it's also a "deal" being made, just like those sneaky politicians do! Get it? It's all about the 'back' part. You're welcome, you simpleton.
