The Naive Bride

A naive young girl goes into the doctor's office. She says:

- Doc, I'm getting married and I'm a little inexperienced, so I'd like to ask you a few questions.

He says:

- All right.

She says:

- All right... what is that thing that hangs between my fiancé's legs?

The doctor says:

- That's the penis. The male organ, the penis.

She says:

- Okay. And what is that big red knob at the end?

The doctor says:

- That's the glans. The head of the penis, the glans.

She says:

- Okay. And what are those two round things, about twelve inches behind the head?

The doctor says:

- Well, lady, I don't know about your fiancé, but on me, they're the cheeks of my ass.
