 Leprechauns are notorious for quibbles, as evidenced in the 1959 movie "Darby O%27Gill and the Little People" where the aging groundskeeper played by Albert Sharpe traps a leprechaun and receives three wishes.As one wish, he requests that the leprechaun make himself visible to the young groundskeeper who has been sent to replace him (played by Sean Connery).When he opens the sack that contains the leprechaun, the young man sees only a rabbit.
