I use to walk to school when I was a kid in grade school with my cousin Eddie and a chubby neighbor kid Frankie. Frankie's mom thought the key to happiness in life was clean bowels. One time we went to pick him up before school and I watched in horror as his mom gave him 5 - count them - 5 tablespoons of Milk of Magnesia. Our walk to school was about a mile and a half.
Later in class he kept letting em fly over and over. He raised his hand and asked sister Rose if he could be excused. She said no, wait until recess, He raised it again ... she said No ...
Then it happened, he blew, the girl behind him screamed. I used my 4th grade training and quickly did a tuck and roll ... the rest of the class raced out of the room like a fire had broken out.
