(NEWSER) – Employees at a Florida Walmart thought there was something weird about the school bus driving around their parking lot at 5am Tuesday. Its driver seemed to be having trouble parking, and the awkward way it was maneuvering made it seem "like he'd never drove one before," one employee explains to the News Herald. So they called police, and a deputy pulled over the bus ... to find a 12-year-old boy driving it. Michael Wade Propst initially said someone asked him to fill up the bus with gas, but later admitted he took it overnight from a residence and drove it 14 miles across Panama City Beach to the Walmart. Deputies arrested him.
