Basketball is a Muggle team sport invented on December 21, 1891 by Canadian Dr James Naismith while he was teaching at the International Young Men's Christian Training School in Springfield, Massachusetts.  Basketball consists of two teams of five that try to score points by throwing or shooting a ball through the top of a basketball hoop. The team with the most points at the end of four quarters wins the game. Harry Potter first compared Quidditch to this sport to Oliver Wood in 1991, though Oliver had no idea what Harry was referring to.
The American National Quidditch team had a signature move called The Harlem Shuffle that was inspired by the sport of basketball.
