While standing in line for the teller, my son had been playing with the rope separating the lines and wandered behind me to the end of the line next to me which had about 3 people in it. At the end of the line was a very tall, long-haired guy dressed in a leather vest, jeans and a t-shirt (very stereotypical bike look). My son stands staring for a minute and then very loudly announces, "Mom, that man has a poopy diaper! We need the diaper bag!" The guy thought it was hilarious and told my son he didn't need a diaper he had just passed wind (not the word he used). I wanted to crawl into a hole but everyone else in the lobby seemed to get a huge giggle out of it.
