Innovations in Personal Hygiene

My friend, John Smith, has been hoping for years that someone would create a product that would dispense some sort of multi-purpose hygienic gel. This all-in-one wonder substance could be used as soap, shampoo, toothpaste, deodorant, and shaving cream. (I may have left something out.) Well, Smith, I just wanted to let you know that the Germans are working on it. They're only up to hair, hand, and body so far, but something tells me the rest is coming any day now.
