Wifey and I rarely shop the grocery together. I usually just wait in the car. When she returns sometimes I help load groceries. One day she was a bit agitated and had to go back in to find something else. Upon her return she was greeted by a lady walking in with her 3 year old son just a smiling at Wifey. The lady said: "Oh look, he's smiling at you", without missing a beat Wifey replied: "He must have gas!"
