Morgan Freeman and Kesha were both on The Tonight Show Starring Jimmy Fallon last night. Fallon had to ask Freeman to recreate the viral sensation from May, in which he showed off what he sounds like after sucking in helium. for her part, Kesha had a bizarre story to tell.

Freeman was on the show to promote Through the Wormhole, which is coming back for another season on the Science Channel. Back in May, Freeman showed off how physics works by changing his trademark voice with helium. Fallon just had to ask Freeman to recreate that. Although he was clearly apprehensive at first, Freeman gave in.

“It’s very undignified,” Freeman told a laughing Fallon.

Kesha didn’t have to take in any helium to make Fallon laugh. She just had to tell an intricate story about breaking into Prince’s house. As Billboard notes, the Rising Star judge said she gave a security guard only $5, which was enough to get in. She gave Prince a demo CD and is still waiting for a response.
