There was a Seinfeld episode about a gang called the Van Buren Boys. Their sign was holding up 8 fingers, because he was the 8th president.
Van Buren s nickname was Old Kinderhook . He often approved things by signing O.K. which is where OK came from. Because he was skilled at attaining his political goals, he was also nicknamed the Little Magician . Van Buren was the first President born as a citizen of the United States.
