Carbo-loading Tool?

Participating in Ultra running often requires sacrifices on the part of our family and friends. I'm always on the lookout for ways to give back to those who support me so unselfishly. I've found something that may help. Gas Eaters are underpants that have an airtight fabric with a hole and filter in the rear end. For air (or gas) to escape it must pass through the carbon filter. The filter removes foul odor!!!. With all the problems preparing for a race, carbo-loading induced flatulence can place that much more strain on relationships.
Gas Eaters may be for more than just carbo-loading. I know that Mark Long and Rich Sexton both remarked that I was fouling the air way too much on Mark and Rich's recent 60-mile training run. However, I don't know if these shorts would be feasible to run in.
Under-Tec also has a line of underwear with replaceable filters. It's very informative to read the many testimonials. We've got Under-Armour, now may be the time to try Under-Tec!
