Ellen DeGeneres may be a hilarious host for daytime TV and the Oscars — but late night? Maybe not so much.

Since David Letterman announced that he’s retiring in 2015, speculation has swirled about who might replace him on the Late Show — and Ellen’s name has always been near the top of the list. So in Thursday’s episode of Ellen, DeGeneres addresses the rumors by giving us a taste of what her late night monologues might be like. (She also kind of shut down the idea that she might take over for Dave: “I am flattered, but I really love doing my daytime show,” DeGeneres said, “But I feel like you don’t really know if you’re good until you try it.”)

After that, Ellen began her opening monologue again, going backstage and hiding behind a curtain — only to struggle with finding her way back onstage. “I haven’t had that much trouble coming out since 1997,” she quipped once she conquered the curtain.

After trying her hand at some (incredibly corny) political jokes, DeGeneres riffed on Letterman’s famous Top 10 list by presenting her top 11 favorite pets — a list she couldn’t actually decide on the order of — before scrapping the entire thing.

“I’ll stick to daytime for now,” DeGeneres said in conclusion, then addressed Letterman by saying, “You’ve made us happy for over 30 years, so what better song to dedicate to you than Pharrell Williams’ ‘Happy’?'” Cue the curtain opening on a surprise Pharrell performance.
