Actor/comic Bill Cosby stopped by “The Tonight Show” Wednesday (March 26), where host Jimmy Fallon had Cosboy tightrope walk across the floor of the studio — carrying Fallon on his back.

It’s completely absurd but also really funny. Also, Bill Cosby is 76 years old, so … be careful with him, Jimmy Fallon!

Below, check out the interview segments before the tightrope shenanigans started. Cosby regales Fallon with stories of how Stevie Wonder is quite the prankster, then Fallon says he can’t help but do his Cosby impression when he’s around the legendary comedian. Hee!

Bill Cosby should be a late-night guest at least once a week.
