Morgan Freeman is known for his lovely voice, perfect for narration and gravitas. But what does that voice sound like on helium? This clip from “The Tonight Show Starring Jimmy Fallon” has the answer.

Despite Freeman seeming unimpressed with the idea of using helium during his interview, the actor and “Through the Wormhole” host took his turn with the balloon.

“It’s very undignified,” Freeman explains in a ridiculously high-pitched voice. Fallon promptly proves this by laughing hysterically at every sound that comes out of his guest’s mouth.

Just think — how amazing would “March of the Penguins” have been if helium had been involved with the narration?
