Ants in my pants

My son was running around the other day. I asked him if had to go potty, he quickly said "No!" So as he is wiggling and running around, I asked the all important question, "Do you have ants in your pants?" He said, "No." Then he proceeded to check in his pants to make sure there were not any ants. First he looked and didn't see any, but he jumped up and ran to the bathroom turned on the light and checked again and confirmed that there were no ants in his pants. I asked "Are you sure you don't have ants in your pants?" He quickly looked again and then dropped his pants to his ankles and said, "See! No Ants!"
