A wealthy person owns a circular house, when she came home from work there was a jelly stain on her new white rug. The only people who were home was the cook, the maid, and her son. The cook said she was cleaning her pots in the kitchen, the maid claimed she was dusting the corners of the house and her son said he was playing with their dog outside. Who is responsible for the stain?
The maid because it is a circular house (you have to pretend that there is no corners). :-)
