VIDEO: Channing Tatum screws up YMCA dance in new stripper footage

(TMZ) -  New half-naked footage of Channing Tatum has surfaced from his man-stripper past - but it's not the panty-melting experience you were hoping for... guy completely BOTCHED the easiest choreography ever - the YMCA dance.

The video was shot during the actor's brief stint as a male stripper in the late 90's - and clearly...  he still had a lot to learn in the ways of Magic Mike.

Check out the footage - Tatum also does some weird tribal thing at the end ... if you're into that sort of thing... this is a judgment-free zone.
