The presidential hopeful already did Letterman's Top 10 list on "The Late Show" after his "oops" gaffe
Perry, who delivered a Top 10 list about his infamous debate "oops" moment on "The Late Show With David Letterman" on Nov. 10, will face a Leno who's gotten plenty of monologue mileage out of the politician's gaffe.
"For a guy who doesn't believe in global warming, Rick Perry was sure sweating last night," Leno said after the debate in which Perry struggled to remember the name of the Department of Energy, one of three departments he said he would eliminate. "I think there's one more thing he can forget too: being president. That's not going to happen."
Check out a video clip of Perry on Letterman, where his excuses for the gaffe including Mitt Romney's handsomeness and Justin Bieber:
