A young apprentice at the Guthrie Theater in Minneapolis was making her debut as a lady-in-waiting in a costume drama directed by the great Sir Tyrone Guthrie. All she had to do was follow the leading lady by six paces on her entrance, stand behind her silently and follow her by six paces on her dramatic exit.
On opening night, she did everything perfectly until the exit. As the leading lady made her grand way stage right, the young apprentice tripped on her train and plunged headlong into the leading lady's ample rear.
After the show, the humiliated apprentice was sitiing at her dressing table, removing her makeup and weeping. Suddenly, in the makeup mirror, she saw the figure of Sir Tyrone sweeping down the hallway past the door to her dressing room. She held her breath for an instant, then went back to removing her makeup. Suddenly his figure reappeared in the doorway in the mirror.
The apprenticed turned to receive his fury.
"Silly cUnt," Sir Tyrone said. "You fell."
