It's the time of the French Revolution, and a priest, a prostitute and an engineer are to be executed by guillotine.  They ask the priest whether he wants to be face up or face down when he meets his fate.  The priest says that he would like to be face up so that he will be facing heaven when he dies.  They raise the blade of the guillotine, released it, it comes speeding down and suddenly stops just inches from the priest's neck.  They take this as divine intervention and release the priest.  It's now the prostitute's turn, and she also opts to be face up, hoping that she will be as fortunate as the priest.  The blade comes speeding down and suddenly stops inches from her neck.  So they release her as well.  The engineer, not surprisingly, also decides to be face up.  So they raise the blade, and suddenly the engineer says, "Hey, I see what the problem is!"
