Got one to add...
We were at Disney (Fort Wilderness) and was just standing there as a mom and dad drive by on their bicycles. Well the dad (in the rear with a childseat on the back) decides to pop a wheelie just as mom turns to look at him. Well, brainiac loses the kid out the back of the bike onto the blacktop pavement. After screaming a whole lot of be nice at dad, it turns out the kid was OK.. just a little stunned after getting the ejection seat (dang near landed in the bushes)!! At the time my husband wanted to go knock some sense into him but the Mrs. took care of him pretty good on her own! Gotta love people-watchin.
