Years ago I was at a Convenience Store standing in line at the cash register. There was a lady in front of me and another man in front of her paying the clerk. I knew a little bit about the guy that was making his purchase. He was a little mentally challenged and usually spent most of his day going from store to store asking the store owners if they needed anything. The area was nothing but little stores and barber shops so his offers were usually appreciated.
As the three of us stood in line the first guy let one rip, right at the lady that was standing in front of me. This effort came while he was paying the clerk and seemed like it was just as normal to him as sneezing. He was kind of a pudgy guy and the noise that came out sounded like a motor boat. It sounded like when you are standing in the shower and you have your back to the shower head with the water running down your back. When you fart with water running down your back and into the crack of your ass it bubbles, just like a motor boat engine running in the water. That was the sound that echoed through this store.
The lady in front of me jumped back and turned to look at me. She had this look of shock on her face and she looked like she wanted me to do something. Unfortunately it was all that I could do to keep from applauding his effort.
