Adapted and excerpted from Stan and Jan Berenstain’s Down a Sunny Dirt Road: an Autobiography, published by Random House in 2002.

Bears on Wheels was a highly unconventional counting book that begins with “One bear on one wheel” (a unicycle).

The story works its way through permutations and combinations of bears on wheels until all participants are unseated in a cataclysmic crash, leaving “Twenty-one on none.”

Bears on Wheels was published by Random House in 1969.
