Well, somebody's gotta say it. It might as well be me. The easiest way to skin a tongue is to stick it on an iron flag-pole or steel rail, in the middle of a cold winter day (temp. around 15 degrees F.) and quickly yank your head back. Peels 'em every time.
After that, I've never had the opportunity to try tongue, mostly because I think my wife would skin me if I brought one home.
