Maybe someone else can fill in the details, but I recall a story around a camp fire at Harris Hill in the early 1990s with Charlie Spratt. The gist of it was a competition between the Fonz and someone else to see who could perform the lowest recovery from a spin in a tandem two seater (cub or citabria or the like). There was more to it, but I don't want to give out any incorrect stuff.
