Stupid things you have done

High school auto shop had a dual post lift that had independent controls. Guy manned the rear post only and propped up his car at about a 45 angle before he looked back.... wasnt me but everyone saw it after the auto shop teacher screamed "STOP!!!!!"

Jacked up a VW bus with the stock screw jack and driver forgot to set the E-brake. Semi blew by us and literally blew the bus forward and rolled it right off the jack. Broke the jack, bus now sitting on rotor. Middle of desert.
