Ben Affleck Tops Matt Damon

Ben Affleck appeared on Monday night's Jimmy Kimmel Live! to promote his new movie, but talk quickly turned sexual when Kimmel brought up his close relationship with buddy Matt Damon.

Kimmel picked up a copy of Variety to show the actor that an ad pushing him for best actor in The Town was featured on the cover -- on the inside cover was an ad pushing Damon for best actor in Hereafter.

"Front, not front," Kimmel joked, flipping pages.

Affleck replied, "You know what we like to call that, Jimmy, in our community? Top, bottom."

The conversation begins at the four-minute mark.
