The Birthday Party is a 1950s "Comedy of Menace" written by Harold Pinter. It concerns a boarding house on The Great British Seaside run by Mr and Mrs Bowles, a Happily Married couple, and their single tenant, Stanley Weber, a former concert pianist who seems to have come from nowhere. Life trudges by slowly until the annoucement of two guests arriving, two men who seem to have some sort of link with Stanley's Mysterious Past.
- Affably Evil: Goldberg
- Berserk Button: Do not call Goldberg "Simey." This may be linked to the fact that it was his mother's nickname for him.
- Blind Without 'Em: Stanley losing his glasses is a major plot point.
- Cloud Cuckoolander: Meg. So much.
- The Dreaded: Goldberg. Hearing that he is coming sends Stanley into Heroic BSoD mode.
- Have a Gay Old Time: "Give me a blow!"
- Kick the Dog: Most of Stanley's scenes with Meg have at least one case of this.
- Multiple-Choice Past: Most of the characters.
- The Munchausen: Goldberg again, Stanley also to some extent.
- Oireland: McCann's background hints strongly at this.
- Only Sane Man: Petey Bowles, but he is too scared to act.
- Sesquipedalian Loquaciousness: Goldberg, to great extent
- Those Two Guys/Those Two Bad Guys: Goldberg and McCann
- The Unseen: The mysterious Monty.
- Villainous BSoD: After Stanley's offscreen torture.
