Jimmy Fallon and Brad Pitt Yodel Atop NYC Rooftops (Video)

Jimmy Fallon and Brad Pitt, yodelers?

NBC's late-night host engaged in a yodeling conversation with the very game World War Z star from two rooftops in New York in a clip that aired during Tuesday night's Late Night With Jimmy Fallon.

The conversation consisted of some small talk -- "Jimmy? What are you doing up there?" "Yodeling … you?" "Same" -- before Fallon congratulated Pitt on World War Z. (All of the "conversation" was in subtitles.)

Pitt then came up with a "crazy idea."

"You wanna try a double yodel?" he asked.

Fallon's reply? "A double yodel? But that's never been done before!"
