Kermit's 501 Fun Facts is a 1995 children's book of interesting and wacky trivia, presented in 501 bite-size chunks. The wide-ranging topics include how yeast works, how far a kangaroo can jump, why the Moon's gravity is lighter than Earth, and the inventor of the donut. There's only one fact in the book about the Muppets -- fact #501 is about Jim Henson making the original Kermit the Frog from his mother's old coat.
