Will Ferrell and Zach Galifianakis appeared on MTV's After Hours With Josh Horowitz to debate some important issues, like whether or not to dress pets in human clothing and foot massages versus back massages. But it was a truly heated topic that surprisingly got "The Campaign" stars to agree on a position: Who is the hotter Hemsworth?

Both actors couldn't deny the hotness of the elder Hemsworth, Chris. "I'm gonna go with Chris, because he's got a body that won't quit," Ferrell says with certainty.

Galifianakis also shows his support for the "Thor" star, but accidentally makes his choice while the trio discuss another issue. Guess he was just too hypnotized by the thought of Chris Hemsworth's solid bod to make a quick decision.
