Before the Vietnam War would pin the death-nail on his presidential legacy, LBJ managed to have quite a sense of humor. Seen here is LBJ’s amphibious car, which he would use at his Texas ranch to play pranks on guests. One stand out prank was taking his guests out for a spin, pretend to lose control of the vehicle as they approached the lake, and shout “The brakes don’t work! We’re going in! We’re going under!” The car would then enter the water where, as guests were trying to prevent their heart from popping out of their chests, Johnson would laugh.
