Worker's Constipation

What the term, "Worker's Compensation" is to Butt-Head on the Beavis and Butt-Head episode, "Work is Death".

{Burger World Manager}: Be careful in the kitchen, Burger world can not afford to pay out any more Worker's Compensation.

Butthead: Uhhh, Worker's Constipation?

Beavis: Yeah, yeah, I get that all the time at work when I can't take a poop.
