The video below is essentially the little kid version of "hold my beer and watch this!"
This little kid decided that he was going to show off to his friends by riding his bike down a long set of steps. But about three steps into his adventure, he decided it was a terrible idea. You can tell that he was second-guessing his decision, because the poor kid screamed, "Call 911!" before careening into a wall and falling off the bike.
Don't let this get you down, kid. You have a future in stunt riding!
