By Katie Mathewson Slide 1 of 14

Remember in high school when that bad boy leaning on his locker would look at you with brooding eyes and your knees would turn to jelly? Yeah, that never really stopped for us.

When it comes to the "Total Recall" star, we think the greasier, the better. And when the Irish accent comes out and he squints at you with those "Yeah, I'm bad but I'd change for you" eyes? Yum.
