Zach Galifianakis and Jimmy Fallon Do the Ol’ Switcheroo on Late Night

Zach Galifianakis and Jimmy Fallon do the ol’ switcheroo and swap roles on Late Night with Jimmy Fallon, where Zach hosts (as Jimmy) and Jimmy gets interviewed (as Zach). It gets a little awkward as Jimmy promotes Zach’s new movie, The Campaign. This is not Zach’s first hosting role, you may remember he had his own (short-lived) late-night talk show in 2002, Late World with Zach and of course, his Funny or Die interview series, Between Two Ferns.
