Mickey Rourke Sticks it to Sylvester Stallone

Looks like Mickey Rourke is really needling Sylvester Stallone.

Rourke slips Sly some ink as the character Tool in the upcoming adventure flick The Expendables, about a team of missionaries who travel to South America to overthrow a dictator.

The film, which was written and directed by Stallone, also stars Jason Statham, Randy Couture, Steve Austin, Jet Li and Dolph Lundgren.

Is that a tough-guy convention, or what?
