Will Ferrell and Zach Galfianakis weren't on the bill for the Warner Bros. Comic-Con panel today, so when they showed up with a surprise trailer for their political comedy The Campaign, audience members scrambled to the microphone to come up with something for the Q&A. One man asked the two stars what real-life political scandals they found funny. "The entire Bush administration," replied Galifianakis, to cheers and applause. "Yeah, that was a funny eight years," said Ferrell, who famously played George W. Bush on Saturday Night Live. He added, "Yeah."
