Morgan Freeman gets silly with helium in a new promo for his show.
Morgan Freeman, you’re a good sport.

You’re a good sport for indulging in Jimmy Fallon’s wild fantasy to inhale helium from balloons and conduct an interview on television.

On Thursday, The Tonight Show with Jimmy Fallon saw its host and the 77-year-old actor recreate a clip Freeman did for his popular science series Through the Wormhole.

Fallon also delivered a bad joke about Freeman and rum.

Watch it all go down, above.

Through the Wormhole airs Thursdays at 10 p.m. on the Science Channel. Morgan Freeman’s new film Lucy opens Friday.
