Monster in the Pocket

[iago]

While on safari in the wilderness of Africa, Professor Jones woke up one morning and felt something in the pocket of his pants.  It had a head and a tail, but no legs.  When he got up, he felt it move in his pocket.  However, he showed little concern and went about his morning rituals.  Why was he so casual?

He had a coin in his pocket.
