Stepping on a Lego is bad don't get me wrong but NOTHING

ONCE I WAS IN A SAINT PATRICK'S DAY PARADE AS A KID AND I WAS RIDING MY SCOOTER and I picked it up slightly off of the ground so it wouldn't hit the bumps in the middle of the street. Then it hit a few of the bumps and spazzed out! The scooter went right in front of me and I tripped, landed ON the scooter, and the whole FRICKEN crowd gasped! My dad had to carry my the rest of the parade because of my scraped up knees and hands.
