Remember, several years ago, that guy who stole a tank in San Diego and drove through a few neighborhoods? He ran over several parked cars and drove through a huge RV. He was dragging light poles and was finally stopped on the freeway when he high centered it on the concrete median. As he tried to free the tank, the police opened the lid and killed him if I recall correctly.
ah.. forgot about YouTube. Here is the clip....
