James Corden and Billy Crystal did a parody of the "faking it" scene from When Harry Met Sally .
In a sketch on The Late Late Show on Tuesday, Corden and Crystal stop by a diner and get to chatting over lunch. Crystal is convinced every talk show host loves to have him on. Corden asks him how he can tell.
When Crystal doesn't come up with a convincing reason, Corden proves to Crystal that talk show hosts are really good at faking it!
