Cunstruction Problems

A construction worker on the 5th floor of a building needed a handsaw.

So he spots another colleague 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 takes his left index finger.. and points to his eye meaning "I", then points 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 f**k is your problem!!! All I needed was a hand saw!".

The other guy says, "I knew that! I was just trying to tell you - I'm coming!"
