The 'It's The Law' meme features the character Mr. Moseby from the Disney Channel series 'The Suite Life on Deck' making a stern and emphatic declaration. The image originates from an episode where Moseby is teaching another character to drive, highlighting the non-negotiable nature of the rules. On the internet, it serves as the ultimate reaction for situations where someone questions a behavior that feels mandatory, such as eating pizza crust or waving at a dog. It perfectly encapsulates the humor of treating minor personal habits or social etiquettes as strictly enforced legal requirements.
