A construction worker on the 3rd floor of a building needs a handsaw. He
sees another man on the 1st floor. He yells down to him, but he can't
hear, so he does sign language.
To do sign language, the man on the 3rd floor points at his eye meaning
"I", points at his knee meaning "need", and moves his hand back and forth
in a handsaw motion.
The man on the 1st floor nods his head, pulls down his pants, and starts
masturbating. The man on the 3rd floor gets so angry he runs down to the
1st floor and says, "What the fuck is wrong with you, dumb ass? I said I
need a handsaw!"
The other guy says, "I knew that, I was just trying to tell you I'm
coming."
