John Gielgud is the Shit Fairy...
"Many years ago, while appearing on Broadway Gielgud was in a yellow cab on the way to the theatre. It had been raining so he was carrying an umbrella. After exchanging pleasantries with the driver, Gielgud was dropped off and made his way to the stage door.
"A few paces away from the cab he was surprised by the previously friendly driver screaming "Ya fuckin fairy, yo forgot yo fuckin wand!".
Gielgud calmly walked back to the cab, collected his brolly, tapped the driver on the head and said 'Turn to shit'.
