ideas to pay for david's college

Great new idea: a device that you can buy at the cell-phone store in packs of three or four. All new buildings, public and private, would be built with them installed. They would hang just inside a bathroom door and signal your cell phone that you have entered the bathroom. Then, if people call, they would get your "I can't answer the phone, I'm in the John" message. Higher-end cell phones would include an option of having a special "In the John" group for people you are willing to talk to on the comode. These phone numbers would be allowed to ring through.
