Get the 21 mug.
The age of majority in the United States due to its stupid laws where not only you have to be 21 to drink, you also have to be 21 to stay at a hotel and rent a car (although some discriminating rental car companies won't let you rent until age 25)
This wonderful vacation is going bad since I can't even get a hotel AT ALL due to their stupid policies saying I have to be 21! This means I have to sleep on the floor, YUCK! Hope they won't check my ID at the bar because I am only 18...Oh wait, they did and I was denied entry...FUCK!
