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, isnt it?

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