McWhat?
Do you remember that episode of SpongeBob SquarePants where SpongeBob had to blow raspberries every time he spoke? Yeah, that episode was creepy as heck, but it’s also one of the show’s classics. Anyway, he had to blow raspberries because the deep-water creatures couldn’t understand his accent.
The same problem exists in every McDonald’s restaurant on the planet. If you don’t begin your answer with a Mc, then the employee won’t understand what you want. This guy was asked whether they wanted small, medium, or large fries with their order, and answering “McYes” was the only way to get their order through.
