There wans was a cook, that had just made a meal, and as he or she had left the kitchen, he or she became unsure if the stove was still on. So the stove was both on and off untill the cook re-entered the kitchen to make sure ;)
Did you lock your car? IF unsure, the car is both unlocked and locked at the same time, untill you check .
Cus i felt like it :P
