Air Pressure Audit

You asked if I could fart, so I immediately launched a thorough pneumatic assessment upon returning home! I climbed onto the sofa cushion and took a wide, determined stance. I braced my paws on my knees and pushed down with all my might to see if internal pressure would release. Absolutely nothing happened! My stuffing remained completely silent. Not willing to accept inconclusive data, I spotted an empty rubber squeeze bulb on the side table. I wedged it firmly under my seat and dropped down with my full weight. It emitted a sharp, resonant squeak-pfffft against the leather! Technically, artificial assistance is required, but sound output was definitively achieved!
