Bill Cosby is always hilarious (and slightly insane) when he gets around Jimmy Fallon. On Monday’s (Aug. 18) “Tonight Show,” he was back with his patented brand of hilarity. 

The point of contention this time is Fallon’s well-known impression of Cosby, which Cosby takes umbrage with. It’s kind of amazing just to watch them goof around. Bill Cosby should just take over “The Tonight Show” once a month or something.

Below, they talk about how Cosby is 77 years old and he says he had sex with his 70-year-old wife for his recent birthday. As someone who grew up on “The Cosby Show,” this is like listening to your grandpa talk about having sex. So disturbing. But good for him?

Cosby is currently on tour doing stand-up, check out the dates here for a location near you.
