Engineers...
During the French revolution a priest, a thief, and an engineer are set to be executed by guillotine.
The priest is selected to go first. As he approaches the guillotine the executioner asks "How do you want to go, face up or face down?"
"Face up," the priest replies, "So that I am facing toward God when I die." They put him in face up, raise the blade slowly to the top and release it. The blade comes flying down toward the priest and STOPS, barely touching his neck. The executioner takes this as a sign from God and lets the priest go.
The thief is up next. "How do you want to go?" he is asked. "Face up worked well for the priest, I'll take that!" responds the thief. He is placed in face up. The executioner slowly raises the blade to the top and releases it. The blade comes flying down toward the thief and stops, barely touching his neck. They let the thief go as well.
Finally the engineer is brought up to the guillotine. "How do you want to go?" he is asked. "I like how face is going today, so I'll take that." he replies. The engineer is placed in face up. The guillotine is slowly raised to the top and just as it reaches the top he points up and yells "Hey! I see what your problem is..."
