The Bald Soprano spoofs the desire to logically pursue the truth in a world that’s patently absurd. At the center of the play are two long communal attempts at detective work. In the first case, the Smiths’ guests, Mr. and Mrs. Martin (who have forgotten one another but feel they have met before), work step by step through the exactly matching details of their past and their current living situations, with mounting surprise at the incredible string of coincidences. When they discover each has a daughter named Alice with one white eye and one red eye, they triumphantly conclude that they are in fact “Donald and Elizabeth,” husband and wife. Yet Mary, the Smith’s maid, then informs the audience that they are mistaken: their respective daughters have white and red in opposite eyes, and so they cannot be the Donald and Elizabeth they take themselves for. This last revelation would seem to stress the importance of total thoroughness in logical reasoning, but its sheer absurdity actually undercuts any faith in such deductions. The Martins have already confirmed that they live in the same apartment and sleep in the same bed, so if they are not in fact the husband and wife they believe they are, then their reality is truly incoherent and resistant to any logical analysis.
In the second instance of detective work, the Smiths and Martins debate the meaning of the doorbell ringing: when Mrs. Smith answers it twice and no one is there either time, she concludes that “[e]xperience teaches us that when one hears the doorbell ring it is because there is never anyone there.” She is proven wrong when the Fire Chief is there at the door after ringing the bell a little later, and he revises her conclusion to say that “[w]hen the doorbell rings, sometimes there is someone, other times there is no one […] Life is very, simple, really.” This conclusion satisfies the crowd; Mr. Martin says it “seems logical.” The joke, of course, is that these sound scientific deductions from experience fail to explain the blatant absurdity of how the doorbell rings when no one is there. Logical reasoning gives the play’s characters a false sense of security about their reality, while in fact it only illuminates the illogical chaos governing their world. The play suggests that the human desire to be certain of what’s going on, despite the impressive logical tools this desire brings to bear, is doomed to fail (and to look ridiculous in doing so) in an inherently random and meaningless world.

Logic, Reality, and the Absurd Quotes in The Bald Soprano
MRS. SMITH: There, it’s nine o’clock. We’ve drunk the soup, and eaten the fish and chips, and the English salad. The children have drunk English water. We’ve eaten well this evening. That’s because we live in the suburbs of London and because our name is Smith.
MR. SMITH [still reading his paper]: Tsk, it says here that Bobby Watson died.
MRS. SMITH: My God, the poor man! When did he die?
MR. SMITH: Why do you pretend to be astonished? You know very well that he's been dead these past two years. Surely you remember that we attended his funeral a year and a half ago.
MRS. SMITH: Oh yes, of course I do remember. I remembered it right away, but I don't understand why you yourself were so surprised to see it in the paper.
MR. SMITH: It wasn't in the paper. It's been three years since his death was announced. I remembered it through an association of ideas.
It is his wife that I mean. She is called Bobby too, Bobby Watson. Since they both had the same name, you could never tell one from the other when you saw them together. It was only after his death that you could really tell which was which.
How bizarre, curious, strange! Then, madam, we live in the same room and we sleep in the same bed, dear lady. It is perhaps there that we have met!
I can therefore let you in on a secret. Elizabeth is not Elizabeth, Donald is not Donald. And here is the proof: the child that Donald spoke of is not Elizabeth's daughter, they are not the same person. Donald's daughter has one white eye and one red eye like Elizabeth's daughter. Whereas Donald's child has a white right eye and a red left eye, Elizabeth's child has a red right eye and a white left eye! Thus all of Donald's system of deduction collapses when it comes up against this last obstacle which destroys his whole theory.
MR. MARTIN: Don't you feel well? [Silence.]
MRS. SMITH: No, he's wet his pants. [Silence.]
MRS. MARTIN: Oh, sir, at your age, you shouldn't. [Silence.]
MR. SMITH: The heart is ageless. [Silence.]
MR. MARTIN: That's true. [Silence.] MRS. SMITH: So they say. [Silence.]
MRS. MARTIN: They also say the opposite [Silence.]
MR. SMITH: The truth lies somewhere between the two [Silence.]
MR. MARTIN: That’s true. [Silence]
MR. SMITH: As for me, when I go to visit someone, I ring in order to be admitted. I think that everyone does the same thing and that each time there is a ring there must be someone there.
MRS. SMITH: That is true in theory. But in reality things happen differently. You have just seen otherwise.
FIRE CHIEF: I am going to reconcile you. You both are partly right. When the doorbell rings, sometimes there is someone, other times there is no one.
MR. MARTIN: This seems logical to me.
MRS. MARTIN: I think so too.
FIRE CHIEF: Life is very simple, really.
Well, then! [He coughs again in a voice shaken by emotion:] "The Dog and the Cow," an experimental fable. Once upon a time another cow asked another dog: "Why have you not swallowed your trunk?" "Pardon me," replied the dog, "it is because I thought that I was an elephant."
Oh, charming! [He either kisses or does not kiss Mrs. Smith.]
MRS. SMITH: We don't have the time, here.
FIRE CHIEF: But the clock?
MR. SMITH: It runs badly. It is contradictory, and always indicates the opposite of what the hour really is.
The polypoids were burning in the wood
A stone caught fire
The castle caught fire
The forest caught fire
The men caught fire
The women caught fire
The birds caught fire
The fish caught fire
The water caught fire
The sky caught fire
The ashes caught fire
The smoke caught fire
The fire caught fire
Everything caught fire,
Caught fire, caught fire.
MRS. MARTIN: Bazaar, Balzac, bazooka!
MR. MARTIN: Bizarre, beaux-arts, brassieres!
MRS. SMITH: A,e,i,o,u, a,e,i,o,u, a,e,i,o,u, i!
MRS. MARTIN: B, c, d, f g, 1, m, n, p, r, s, t, v, w, x, z!
[The words cease abruptly. Again, the lights come on. Mr. and Mrs. Martin are seated like the Smiths at the beginning of the play. The play begins again with the Martins who say exactly the same lines as the Smiths in the first scene, while the curtain softly falls.]
