A guy in St. Louis was driving to work on Hwy 144 when he heard a 'pop'! . He thought it sounded like a flat tire, though his ride wasn't affected. After pulling over, checking the tires and finding them intact , he opened the hood to look at the motor. Before the hood was even all the way open he jumped back in shock and knocked his head on the partially opened hood, unable to believe what his eyes were seeing! this has to be right up there at the top of the list of unusual but verified 'Reasons I was late for work'!
