Minor coontact, I was walking across the parking lot to the grocery store, and there were a couple of niglets or teenapers on their bikes doing wheelies and other "look at me" tricks. One of the nigs made a sharp turn all of the sudden and cut across my path only about 5 feet away. It then proceeded to pop a wheelie and then climb up and stand on top of the seat. Unfortunately it managed to make it back down safely.
