SBD-Silent But Deadly. Everyone knows a Fart Ninja... If you don't know one, you may be one. They casually crop dust the room with a paint peeler as they stroll through. Suddenly your nose hair curls, your eyes water...the Fart Ninja has struck again. When cornered, The Fart Ninja will either deny or blame the dang dog. Perfect for tooting, flatulent, wind-breaking, farting, cheese-cuttings and gassy friends whether they are truly silent in their art form, or perhaps not so silent.
