Mitt Romney has refused David Letterman's multiple interview requests, so the host has resorted to hiring professional actors to simulate what it would be like to interview him. Earlier this week Jack Black chatted with Dave in a very Romney-esque pair of jeans, and on Thursday's show Matthew Broderick took on the role. His Mitt was surprisingly punchy, in more ways than one. When Letterman asked "Mitt" what he thought of his debate performance, he shot back, "What are you drunk? I nailed this son of a bitch!" He also repeatedly fist bumped the host, imploring him to "punch the rock."
