Yeterday in Torts my professor told us a story that her mother told her - when she was small, her mother and a group of friends would get together and discuss parenting techniques. At one of these meetings, while discussing potty training, a woman from another country said that they never had problems with potty training in her country. When all of the other mothers asked in awe how they solved the problem over there, the woman said, "Oh, well when they are in potty training, we just light a match under the kids and say, 'don't make a mess'...and they never make a mess." Needless to say, she was not invited back to the discussion group. BUT finally, I have figured out where the phrase "Light a fire under his ass" comes from!
