The owner of the mini golf course tells Stu and Drew they "both lost" when they fail to make a hole-in-one on the final hole. However, since the two of them are playing each other (and each other alone) there is no way they can both lose. The closest this could come to happening is a tie, but a tie is not the same thing as a loss (likewise, it's possible the owner equates failing to get a hole-in-one on the final hole with losing, but it's still the incorrect way of putting it).
