Bill Cosby was dead silent this weekend when Weekend Edition host Scott Simon asked him about those pesky rape allegations, but he hasn't always been—in fact, he jokes about drugging women's drinks an early stand-up routine that loosely corresponds to his accusers' stories.

The Village Voice's Alan Scherstuhl tracked down the 1969 routine, where Cosby discusses "Spanish fly," a secret substance boys start hearing about "on the corner." [According to legend, it acts as an aphrodisiac when slipped into a woman's drink at a frat party. In reality it's an irritant that's sometimes deadly.]

It always happens when you're 13, only when you're 13 on up 'til when you get married. Guys standing around and talking about Spanish fly.

"You know anything about Spanish fly?" "No, tell me about it."

"Well there's this girl Crazy Mary, you put some in her drink man, she, 'Haaaaaaaaaaaaah.'"

"Oh yeah, that's really groovy man, Spanish fly is groovy, yeah."

From then on, any time you see a girl: "Wish I had some Spanish fly."

Go to a party see five girls standing alone: "Boy if I had a whole jug of Spanish fly, I'd light that corner up over there. HAAAAAAH."

Cosby intimates his interest in date rape as a 13-year-old continued into adulthood, explaining his excitement when he found out his 1960's TV show I Spy was filming in Spain.

A childhood dream come true... I said, "Hey Bob, you know what I'm going to pick up in Spain? He said, "Spanish fly."

If Cosby's slip it in her drink routine sounds vaguely familiar, it's because most of his accusers say he slipped something in their drink:

In his bungalow he made me a redeye, and I began to tell him about the earthquake Los Angeles had just had and the sound it made. He liked my ideas for an earthquake bit. The next thing I remember was coming to on his couch while being undressed.

He sent a limo to pick me up and I was dropped off at the Sherry Netherland Hotel and went up to his suite. I remember noticing that his leather shaving kit was filled with bottles of pills, and thinking that this seemed odd. He was, of course, very friendly and I, of course, was very uncomfortable. He made me a redeye, and I, being nervous and dealing at the time with an alcohol problem (I've been in recovery since 1988), drank it. In the car I had something else to drink, but was already beginning to feel a bit stoned.

He invited me to his New York brownstone for dinner. Staff was there. We ate in the kitchen. I had one glass of red wine with dinner. My next recollection is me, coming to, slumped over the toilet bowl, throwing up. I was wearing a man's white t-shirt and my panties.
