In a joint segment that opened both Global’s “The Late Show” and “The Tonight Show”, Colbert is at his desk writing that night’s monologue when he gets a video call from Fallon.

Soon enough they’re chatting about the things Donald Trump said about them at a recent rally, calling them, “no-talent, lowlife, lost souls.”

Colbert responds, “That’s not right… that’s Conan!” and quickly gets O’Brien on the call, only to find him in the middle of shaving his chest and hilariously unaware that Trump is even president.
