Here a joke for your day; 4 high school students was having a party the day before a big test.

The next day when they drive to the school ( of course ) They were late to the test.

The teacher asked why they were later, their answer was a flat tier.

The teacher thinks about and said you guys can take the test tomorrow.

The next day the 4 students sees 1 question, it read.

“Which tier was flat?”
