According to Pinter's official authorised biographer Michael Billington, the sketch (and the scene in The Hothouse) was inspired by and reproduced details of "his own experience [as 'a guinea pig']" at the Maudsley Hospital in London" in 1954, in which he took part to earn "ten bob or something" and about which he told Billington: "The Hothouse was kicked off by that experience.
Applying for a job, Lamb, who identifies himself in the dialogue as a "physicist" (231), is given a psychological test by Miss Piffs.
Before he has recovered, Miss Piffs bombards him with social, medical and sexual questions (232–34), in response to which he says "in a high voice", "Well, it depends what you mean really—" (234).
