President Lyndon B. Johnson pranked his visitors on his ranch in Texas by driving his car into a lake! Johnson is remembered fondly for his crazy, scary trick at his popular ranch in Stonewall, Texas. In the 1960s, in Germany, only 3,878 Amphicars were built. Amphicars are vehicles that can drive on both land and water. Because of the small number of Amphicars, a small number of people knew about this particular vehicle. Johnson would trick his guests by giving them a tour around the ranch in his Amphicar and ended it by taking them on a hill. Once at the precipice, he would scare the guests by telling them that the brakes had stopped working and slowly rolled down the hill into the water. Now, only about 600 Amphicars remain in the United States.
