Two roofers, Larry and Joe, were on the roof laying tile, when a sudden win gust came and knocked down their ladder.

“I have an idea,” said Larry. “We’ll throw you down, and then you can pick up the ladder.”

"What, do you think, that I’m stupid?" replied Joe. “I have and idea! I’ll shine my flashlight, and you can climb down on the beam of light.”

Larry wasn't having it. "What, do you think that I’m stupid? You’ll just turn off the flashlight when I’m halfway down.”
