Give others fair warning with one of Gassun Limited's trendy OtisWear Apparel T-Shirts. With The Original Gas-O-Matic® logo on the front, this shirt spells it out clearly on the back with the warning to "Stay Back 300 Feet!" Other apparel designs include two "Who Farted" shirts featuring the company mascot, Otis, and a gray athletic apparel design. All T-Shirts are made from high quality 100% pre-shrunk cotton.

The Original Gas-O-Matic® is a mechanical wind-up fart toy with an amazing repertoire of fart sounds sure to turn heads and disgust innocent bystanders! No batteries necessary. Simply wind the center spinning device (aka the "Sphincter") of the Original Gas-O-Matic®, hide it under your leg, then give that umistakeable "fart lean" and "rip it". The Original Gas-O-Matic® is proudly made in the USA using safe, high quality and durable materials for long lasting fun!

For use with the Gas-O-Matic®, these replacement sphincters are available to replace worn out sphincters due to age and continual use.  Each package contains two replacement sphincters made using high quality, high tech, vinyl coated stainless steel and durable polycarbonate plastic center, with 100% silicone high speed bands. These sphincters were scientifically engineered using Sphysics (Sphincter Science and Physics) to provide you with the most authentic flatulent sounds.

It is certain that everyone knows at least one "special someone" - whether it be your spouse, child, co-worker, boss, neighbor, or relative - who loves to fart. The Official Fartstrong Foundation wristband allows the wearer to share this love with the world, while also creating awareness about those less able to share their gift of audible flatulence with others (also known as Auditory Flatulence Deficits, or AFD). The makers of The Original Gas-O-Matic® are committed to stamping out AFD by encouraging others to "Live Long and FartStrong!"
