It's 1991, and Bill Cosby is one of the most famous and powerful actors and entertainers in the world.

In November, he's on the Larry King live show promoting a brand new autobiography called Childhood,

and sharing some of his favorite jokes.

The old story was, if you took a little drop, it was on the head of a pin.

It's a drop in a Coca-Cola, it doesn't make it, and the girl would drink it and show how low America.

Cosby's doing his Spanish fly routine for Larry King, one which he's performed on stage since the 1960s.

In it, Cosby jokes with the audience about slipping an Afro-Dijac into a woman's drink, a drug that renders her helpless after a couple of sips.

You know anything about his Spanish fly? No, tell me about it. Well, that's his girl, Crazy Mary. He puts some in her drink, man.

Go to a party, see five girls standing along. Boy, buy her a whole jug of Spanish fly like that, go on her up over there.

I didn't know anything about the Spanish fly routine back then, and the media didn't pay much attention to it either.

By the time he was telling the joke to Larry King, Cosby had written best-selling books about parenthood and made the world laugh with family-friendly comedy routines.

He was a humanitarian and philanthropist who had donated millions to charities and colleges alike.

And his portrayal of Dr. Cliff Huxdable on the Cosby Show had earned him the warm and fuzzy moniker of America's dad.

Cosby's long, seemingly happy marriage to his wife Camille only added Luster to a picture-perfect image of a devoted husband and father.

There was never a hint, not even a whisper, that he wasn't who he seemed to be.

But that Spanish fly routine was there, hiding in plain sight, a pin-pric detail in the broad tapestry of his career all this time.

Cosby talking about slipping drugs in the women's drinks.

If we'd only known back then, it wasn't just a joke.

It was only later that we learned Bill Cosby had been leading a double life, cultivating friendships with young women by promising them mentorship and connections.

For nearly half a century, he groomed them and their families, building relationships and gaming their trust before drugging and sexually assaulting them.
