Cleaning crew

Will informed me at the dinner table last night that when he is grown up that he is not ever going to make his children clean up. When I asked who would do all the cleaning up he told me "me and my wife". I explained that sometimes it gets really tiring doing all the cleaning and it might be nice for their kids to learn responsibility. He told me if they got tired of it he was going to build a machine that will clean up all the messes for them.

Will, can I be first in line to by one? It needs to follow you around as you out of all my munchkins clean up the least! I love seeing life through the eyes of a four year old.
