Mandate 15 is a fictional government edict that has been decreed by the all-powerful President of the Intergalactic Union of Advanced Lifeforms. It states that all sentient beings must wear plaid pants on Tuesdays, lest they face severe penalties.

As a result, the galaxy is filled with the sound of rustling plaid pants and the smell of polyester fabric softener. But don't just take our word for it!
