Where does the phrase, "Its your turn in the barrel" come from?

[Hermann Cheruscan]

I've heard supervisors use the phrase "it's your turn in the barrel" when they are giving someone a difficult, undeserved assignment. Its almost as if they are saying "its your turn to get screwed".

Has anyone else ever heard this phrase before?

I wonder if it has anything to do with that old joke about a ships crewmembers taking turns inside the barrel, pleasuring their fellow shipmates.
