Having a Cup of Coffee

John was sitting in a cafe. The waiter had just brought a cup of coffee to the man sitting at the table next to him. The man drained his coffee into the vase on the table and ate the cup. He only left the handle. Then he paid and left the cafe.

"Did you see that?" John asks the waiter. "This man drained his coffee into the vase and ate the cup. He only left the handle. Strange, isn't it?"

"That is strange indeed," replied the waiter. "The handle is the best of a cup."
