Next week, seven-year "Daily Show" correspondent John Oliver will take over for Jon Stewart as host of the show for three months. The only problem is, he has no idea how to interview actors.
"It's an American institution, and I just have to try not to destroy it," Oliver joked on Tuesday night's "Late Show" where he sat down with David Letterman to talk about his daunting new gig.
Luckily, Letterman had some solid advice to offer Oliver on how to talk to actors without making fun of them. Watch the video above to hear exactly what Oliver will be asking his guests when he has no idea what to ask.
Oliver takes over "The Daily Show" next Monday, June 10.
