In a small town there lived a gypsy psychic, who was known to read minds, do divinations etc.
One day, she went to shop for clothes.
After trying all kinds of outfits, a sales person approached her and asked if she can bring her some things.
"Sure." Said the seer, and the girl went to get her dresses.
When she came back, the psychic looked at the clothes and then raised an eyebrow.
"There is no way these will fit me, they are all 'Large'!"
"I've been working at this a while," said the sales girl, "believe me, I think these will fit you."
"Nope. No way." said the seer.
"How do you know if you haven't even tried them on?" Said the frustrated girl.
"Trust me," said the seer, "I'm a medium."
“Watching a dog try to chew a large piece of toffee is a pastime fit for gods. Mr. Fusspot’s mixed ancestry had given him a dexterity of jaw that was truly awesome. He somersaulted happily around the floor, making faces like a rubber gargoyle in a washing machine.”—Terry Pratchett
