On Tuesday's Late Night With Jimmy Fallon, the World War Z star and the late-night night host sang their hearts out from the rooftops of NYC buildings! (OK, to be fair, there might've been some lip-syncing to pro-yodelers, but let's just pretend it's actually Brad and Jimmy.)
In the funny clip, Jimmy is surprised when, as he yodels out over Manhattan, Brad responds with a yodel of his own. Then, Brad asks if his fellow rooftop singer wants to try "a double yodel."
Jimmy seems apprehensive at first, saying, "A double yodel? But that's never been done before!" But that doesn't stop the duo from pulling off an awesome, double yodel in perfect harmony.
Get it, fellas!
