A woman goes to the doctor...

The doctor tells her to get undressed and lie on the table. She gets up there and put her feet in the stirrups.
The doctor starts playing with her titties and the doctor asked, "Do you know what I'm doing?"
She says, "Yeah, you're checking me for breast cancer."
He says, "Yep!" and continues with the examination. Then he starts playing with her pussy. Again he asks, "Do you know what I'm doing now?"
She says, "Yeah, you're checking me for uterine cancer."
He says, "Yep," and thinks, 'This bitch is so fuckin' dumb...I gotta go all the way!"
So, he sticks his dick in her and starts pumping like nobody's business.
"Know what I'm doing now?" he asks.
She says, "Yeah, you're catching the clap...I only came in for a shot!"
