The maths teacher and the English teacher went out for a quick pizza after school.

“How long will the pizzas e?” asked the maths teacher.

Sorry, Sir” replied the waiter, “we don’t do long pizzas, just ordinary round ones.”

Waiter: “Tea or coffee, gentlemen?”

1st customer: “I’ll have tea.”

2nd customer: “Me, too – and be sure the glass is clean!”

(Waiter exits, returns)

Waiter: “Two teas. Which one asked for the clean glass?”
