I used to think that when people were immersed in the baptistry at church, the floor under the water would open up and these big metal clamps would grab them and pull them below the floor. Simultaneously, a robot that looked exactly like them would pop up from under the water. Then the robot would take their place in life, but nobody except the pastor knew about this.
