Bart Simpson, suffering from paranoia due to the behavior-modification drug Focusyn, infiltrated the base, got to the shower room, and stole a set of tank keys from the pants pocket of a soldier who was taking a shower. Bart then hijacked a tank and drove it through Springfield, stopping at Springfield Elementary School when the tank ran out of fuel. Marge asked Bart to get out of the tank, and he said he would after blowing up just one thing.
