How Stephen Colbert, Jimmy Fallon and Conan O'Brien's joint cold open came about
Both Stephen Colbert and Jimmy Fallon's late-night shows ran the same cold open Tuesday night, a first time for both. The idea was Colbert's. He called Fallon Tuesday and the "Tonight Show" host quickly agreed. Jimmy Kimmel was on vacation and totally off the grid, but Conan O'Brien also agreed right away to join in.
