A guy goes to his eye doctor for an examination. They start talking as the doctor is examining his eyes. In the middle of their conversation, the doctor casually says, "You need to stop masturbating."
The guy replies, "Why Doc? Am I going blind?"
The doctor says, "No, but you're upsetting the other patients in the waiting room."
Doctor: "Look, you're going to have to stop masturbating."
Patient: "Why?"
Construction worker on the 5th floor of a building needed a handsaw. So he spots another worker on the ground floor and yells down to him, but he can't hear him. So the worker on the 5th floor tries sign language.
He pointed to his eye meaning "I", pointed to his knee meaning "need", then moved his hand back and forth in a hand saw motion. The man on the ground floor nods his head, pulls down his pants, whips out his chop and starts masturbating.
The worker on 5th floor gets so pissed off he runs down to the ground floor and says: "What the fuck is your problem! I said I needed a hand saw!"
The other guy says: "I knew that! I was just trying to tell you – I'm coming!"
