A man in an upstairs appartment worked the night shift and continually work the occupant in the appartment below by taking off his boots and tossing them across the room. After complaints, he agreed to change his way but, on returning home early one morning, he threw one boot before remembering his promise.
He gently placed the second boot beside his bed. Twenty minutes later, his neighbour pounded on the dooe. "For God's sake," he screamed, "throw the other boot so I can get back to sleep!"
