A lot of it is folklore, for that matter. I was brought up on a slightly different version of the W G Grace story told in that Mail article linked by Ed: that Grace was clearly stumped, but the square leg umpire said emphatically, "Not out"; then, turning to the wicket-keeper, added, "And you look here, young man; all these people have come here to see Dr Grace bat, not to watch your monkey-tricks!"

Same story in two different folkloric variants? Or two different occasions? Or never really happened, but se non è vero, è ben trovato ?

Who can tell?
