Look at all the dials on the oven to make sure it’s off. Keep looking at the dials until the rest of the check is finished.
Put your foot right next to the oven so it’s actually in contact with it. Now imagine a giant sheet of ice crusting over the controls working it’s way down over the entire oven. You can hear it crusting over as well. Make up a sound that makes sense to you, it’s your imagination.
Since your foot is right next to the oven it also becomes covered within this crust of ice. You don’t stop looking at the oven dials though. You see your frostbitten foot purely in your imagination. Your foot is now frostbitten and stuck to the frozen oven. Now physically pull your foot away from oven (actually physically do this.) As you pull your foot away you can hear the ice tearing. Then imagine a special alligator boot slipping onto that foot. Right at the tip of this boot is the head of a mechanical alligator.
Then imagine ice crusting over this special boot. The head of the mechanical alligator is chomping away biting into its frostbitten teeth. Now should you worry that you’ve accidentally left the stove on all you have to do is remember that special frozen boot chomping away.
