Jon Hamm Teams Up with Will Ferrell and Zach Galifianakis to Drop the Hammer on Jon Stewart

Will Ferrell and Zach Galifianakis were on The Daily Show last night to promote their upcoming comedy The Campaign. The pair, who have been promoting the film for a few weeks now, grew frustrated with Stewart's expected, lame-ass questions and, rather than sit there and take it, decided to gang up on him. Stewart, however, was prepared to go Hard as a Mothafucka and had what he thought would be the perfect teammate to back him up. Enter Handsome.
