Brian Conant, doing chemical warfare training drills for Hawaii's National Guard five years ago, realized that his protective, charcoal lined suit was successfully keeping his flatulence from smelling. After coming home from training he determined to make a charcoal underwear insert that would do for others what chemical warfare suits had done for him. And so he has, with little underwear models for doggies, too. You can read about this marvelously, uh, cheesy, invention in today's St. Paul Pioneer Press.
