Panel 1: A (wheelchair driving) guest is shown, a guide, and a machine (the predictor). The guide says "This is our predictor. It can look into the future. If you press the button, the lamp will light two seconds in advance. If it does not glow, you will not press the button in two seconds." The guest says: "I can't believe this." -- Panel 2: The guest says "Let me try" and starts to reach with his hand for the button on the predictor. -- Panel 3: The predictor machine spits out fire on the guest. -- Panel 4: Only ashes are left of the guest. The guide has a broom and sweeps the ashes.
