Bill Cosby appeared on The Tonight Show Starring Jimmy Fallon on Monday and showed us that his age certainly hasn’t caused any drop off in his sense of humor. Besides giving Fallon a hard time about impersonating him, the former star of The Cosby Show talked about his recent 77th birthday, which apparently involved sex.

You read that right–the man many know as Cliff Huxtable talked about getting birthday sex.

Before we get down to the nitty gritty, Bill Cosby started out his appearance on The Tonight Show innocently (and perhaps confusingly) enough by joking around about driving.

“We’re here! We’re here on The Fallon Show and we’re waiting for the gas pedal and the clutch and the brake,” Cosby said. “Too many people have hit the deer, and the deer always win. But the ones I don’t understand, I don’t understand the intelligence of a moth.”

Check out a clip from Cosby’s appearance below.

And now for the good stuff.

Bill Cosby turned 77 last month, on July 12. When Fallon talked to Cosby about his birthday, Cosby revealed that he got a certain gift that many of us wouldn’t expect for a 77-year-old to get–or at least talk about getting. Check out the clip below.

In case you missed any of that, Fallon asked Cosby, “Did you get cake?”

“No, I got my wife,” Cosby replied. “The most frightening thing at age 77 is to hear your wife, who is seven years younger than you, say ‘Keep going!'”

Let’s just say that the reactions to the 77-year-old bringing up his sex life on TV rather varied. First, we had folks who thought The Cos talking about sex was the funniest thing that has happened all month.

And then there were those who were rather disturbed at Cosby’s revelation:

Bill Cosby is talking about having sex with his wife and it's destroying my childhood @FallonTonight

Funny or disturbing, it’s safe to say that the younger crowd won’t look at the Jell-O pudding man the same again. In the meantime, check out Cosby’s decision to develop a new sitcom for NBC. There’s no word on when we can expect the new sitcom yet, but given Cosby’s comments on The Tonight Show, perhaps we can expect it to be a little raunchier than what he typically does.
