Subtle Butt: Does exactly what it says on the tin

A little while ago, David Sedaris reported to The Stranger that a flight attendant had told that "Us flight attendants, we get so gassy on the airplane we end up farting as we're going up and down the aisles of the plane. We call that 'crop dusting.'"

Perhaps they need Subtle Butt, a product that ruined my morning as I hit up drugstore.com. Here it is, along with instructions quoted verbatim.

Directions

1. Peel off adhesive and stick Subtle Butt onto the inside of your underwear or pants, exactly where you think it goes.
2. Go for it, Let'er rip, Have at it, Cut loose, Break wind, Gas it up
3. When you're done wearing Subtle Butt, remove and discard. If any adhesive traces remain, use a damp cloth for removal.

Tips for Success:

1. You want all the gas to pass through Subtle Butt. So do what you need to do to ensure none sneaks around the edges.
2. Subtle Butt can be applied to thongs by wrapping and securing it around the back.

Update: Here's a YouTube video with more detailed instructions. Determining the efficacy of the product itself is left as an exercise for the reader.
