Oh gross! Yeah, I heard that one before!
Alright, so a single guy moves into a new town. One night he's hanging out with some guys from work, so he says "I'm new here, I need to finnd a hooker, you guys know any good ones?"
So one of his buddies whips out his cell phone and calls this lady, and tells her to come to the bar, and then turns to the guy and says "This hooker is amazing, she'll suck your dick and sing "The Sound of Music" at the same time!"
"Holy crap, how does she do that?"
"No one knows, she makes you turn off the light."
So anyways, this hooker comes over, and they go back to the guy's house, and she makes him turn off the light, and starts sucking his dick and singing "The Sound of Music" at the same time (and she was quite fantastic at both the singing and the sucking). After she was done, he asked her how she does it, and she says "I'll never tell".
But the next day it's just bothering the hell out of him, how the hell she was able to sing "The Sound of Music" while sucking his dick. So he calls her up to come back that night. So anywho, they get back to it, and she's sucking his dick and singing the sound of music, and then the guy switches on the light, and the woman screams and runs out of the room, leaving all of her stuff, which was a dress, a bra, shoes, and a glass eye.
