The Wheel That Ran Away
As an adult, this guy told a tale about how when he was a kid he tried to perform a wheelie, you know, that famous trick when a person rides their bike for a short distance with the front wheel raised off the ground.
Well, that was certainly his intention, but his bicycle had a mind of its own when the front wheel disconnected from the rest of the bike. Since no one believed this happened, he shut up all the haters by uploading a photo of the incident.
