"There was a co-worker who bought a new car when gas prices were high and he constantly bragged about how much money he was saving and how great his gas mileage was. A co-worker decided to play a prank and each day he snuck out to the parking lot and secretly topped off his gas tank.

The daily bragging continued and after about two weeks we stopped secretly adding gas to his new car. Suddenly he stopped bragging about his gas mileage and how much money he was saving.

After another couple of weeks, we asked him for an update on the car. He told us he sold it because it was a piece of sh#t and his gas mileage decreased drastically.

We never told him about the prank."
