Morgan Freeman Sucks on Helium Balloons With Jimmy Fallon (Video)

The actor transformed his iconic voice into a squeak on "The Tonight Show," while Justin Theroux told Jimmy Kimmel that he used to make snow cones in a Japanese circus.

Jimmy Fallon welcomed Morgan Freeman, executive producer of Through the Wormhole with Morgan Freeman (who made sure the host read out the full title) onto The Tonight Show on Thursday, and made him sound like never before.

"Everyone loves your voice, but I always wondered what your voice would sound like on helium," revealed Fallon, before pulling out two bright red balloons filled with the gas.

It took a few times for them to get the right squeakiness, until Fallon asked: "Do you ever want to go to space?" and the Oscar winner squealed in reply, "I shouldn't be doing this … it is very undignified … I am never coming back."

Blue-haired Kesha next revealed how she broke into Prince's house by "cruising up in her dead grandpa's car, and then trolloped up a mountain," said the Rising Star expert. "Everything was purple velvet, so I was very pleased."

While his life with Jennifer Aniston is a circus, Justin Theroux revealed on Jimmy Kimmel Live! that he did actually once work in the Ringling Bros. circus — making snow cones in Tokyo, Japan.

"I don't speak Japanese but I can make snow cones in Japanese," the Leftovers star told Jimmy Kimmel, while claiming that he was a bad boy beneath it all. "I've got some skeletons. You can't come into Hollywood without a couple of mug shots under your belt."

Angie Harmon later confessed that she had a teenage crush on John Taylor from Duran Duran and claimed that he once winked at her, which she was very embarrassed about when she met them years later at an A-list dinner. 

Over on CBS, David Letterman took on a serious tone when he welcomed U.S. Army Staff Sgt. Ryan M. Pitts, who is only the ninth living service member since Vietnam to receive the Medal of Honor.

Seth Meyers had Hank Azaria on Late Night, where the multi-talented actor revealed that he felt guilty for turning his son into a New York Mets fan.

"I feel bad for him, I have guilt over it. I need someone to support me in my suffering," said the Spamalot on Broadway star, who went on to joke: "If you are a straight male actor, I advise doing musical theater."
