A janitor at a Texas medical clinic is lucky to be alive after a freak accident.
77-year-old Manuel Mendoza was moving a chair in the clinic's waiting area when a tire crashed through the window and smashed into him, sending him flying to the floor.
The tire had apparently flown off a truck on the nearby freeway, rolled through the parking lot and then hit the clinic.
Incredibly, Mendoza was not seriously hurt.
