The final moments of GYPSY when Louise exits upstage and Rose follows her..then turns around and looks out into the audience one last time, then closes the door. Wow.
Also, in TABOO in the Selfridge's scene between the makeup artist and George/Marilyn, ending with "Well it's a pity it doesn't F*CKING work then, isn't it?!"
The end of RENT when Mark's movie is playing on the wall, then at the very end when Angel runs back on to join the cast. Not matter how wretched the cast is at that time, it never fails.
