Robot
Two friends meet in the office of one of them, a notorious techo-geek.
"Hey, bud, how are you?"
"I'm good. Congratulations, that new secretary of yours is beautiful!"
"Well, I'm glad you like her. Believe it or not, she's a robot!
"No way, how could that be?"
"Well, She's the latest model from Japan. Let me tell you how she works. If you squeeze her left tit, she takes dictation. If you squeeze her right tit, she types a letter. And that's not all, she can have sex, too!"
"what! You are kidding, yes?"
"No, she's quite something, Tell you what, you can even borrow her"
So, his friend takes her into the restroom and is in there with her for a while. Suddenly, he hears him screaming "Eeeeyaaaaa! Heeelp Ooooooh! Aaaaaaah! Eeeeeeeeeeeaaargghhhh!"
The guy says, "Sugar! I forgot to tell him her ass is a pencil sharpener!"
