Engineer joke:

A rabbi, a priest, and an engineer were sentenced to die by guillotine. The priest went first. The executioner asked if he had any final requests.

"Yes, I do," he said. "I want you to put me in there face up, so that the instant that blade falls I can see the face of God." No one could see anything wrong with that, so the priest was positioned face-up and the guillotine was activated. But the blade didn't fall.

"It's not your day to die," the executioner said. "Go your way."

The rabbi was next, and when asked if he had any final requests, he replied that what the priest had said sounded pretty good to him, so he wanted to go face-up also. Once again, the blade didn't fall.

"God has spared your life," the executioner said. "Go your way."

When the engineer was brought up, he was asked if he wanted to go face-up. "Sure, whatever," he said. But as the executioner prepared to try to drop the blade one more time, the engineer, who had been staring up into the apparatus, called out - "Wait! I see the problem!"
