X was invented by Y. Once a rubber ball was bouncing underneath a table and X tried to fetch it while it was bouncing . Usually X would have been reprimanded for disturbing activities when there was company in the house, as there was then. But this time his manner of fetching the ball created an uproar of laughter from his mother's friends. Stooping with full-bended knees, but with his back and head vertical, he managed to fit under the tabletop while scooting forward reaching for the ball. This squatting manner was requested by members of the family many times thereafter for the entertainment of visitors and soon, from their appreciation and encouragement,X looked forward to the ritual.  Soon after it was forgotten , X remembered it during a show . Identify X and Y .
