You don't need anybody to tell you who you are or what you are. You are what you are!
During World War II, a German U-boat was sunk by a truck. The U-boat in question attacked a convoy in the Atlantic and then rose to see the effect. The merchant ship it sank had material strapped to its deck including a fleet of trucks, one of which was thrown in the air by the explosion, landing on the U-boat and breaking its back.
