There was once an establishment called the Merci Tea Company. Their proud boast was that their customers thanked them for having all possible types of tea. One day, a customer came in, and asked for a cup of tea made from koala bears. After a short delay, a cup of this brew was given to him. "What's this?", he exclaimed. "There's little bits of fur floating around in my tea."
"Sir", the proprietor said, "The Koala tea of Merci is not strained."
