Sewage happens
A few years we went out to eat with a group of friends. I had a big steak and sometimes that can cause real bad gas. After supper we decided to visit the local Dairy Queen. As my wife and I were walking in a monster amount of gas erupted from my stomach. I figured I had better just keep walking as it was so bad I really didn't want anyone to know it was me. So I just kept trucking on hoping it would dissipate. Well turns out that one of the couples we went out to eat with was about 30 seconds behind me. I slipped into the restaurant and acted like nothing happened. It was very busy. So anyway we all got our ice cream and sat down. Then the lady that followed me in started to complain about the sewer smell. She had asked for the manager to request that he clear out that backed up sewer smell. About that time I just exploded with laughter. I explained exactly what happened and we all laughed like crazy. My memory of sewer gas.
