There was this construction worker on the 3rd
floor of this unfinished building.

He needed a hand saw, but was too lazy to go down
and get it himself, so he tried to call his fellow
worker on the ground to get it for him, but this
guy could not hear a word he said. So he started
to give a sign so the guy on the ground could
understand him.

First he pointed at his eyes (meaning "I") then
pointed at his knees (meaning "need), and moved
his hand back and forth describing the movement of
a hand saw.

Finally, the guy on the ground started nodding his
head like he understood and dropped his pants and
started to jerk off.

The guy on the 3rd floor got pissed-off and ran
down to the ground and started yelling at this
guy, "You idiot, I was trying to tell you I needed
a hand saw."

The other guy replied, "I know, I was trying to
tell you that I was coming."
