The example is from a Pete & Dud sketch. Pete is describing to Dud a situation from Neville Shute's A Town Like Alice. A pilot approaches a woman on a runway; a woman whose "busty substances" are outlined underneath her dress bay a shower of rain and the rushing wind from the propellers of a plane.
Dud: What happened after that, Pete?
Pete: Well, the bronzed pilot goes up to her and they walk away, and the chapter ends in three dots.
Dud: What do those three dots mean, Pete?
Pete: Well, in Shute's hands, three dots can mean anything.
Dud: How's your father, perhaps?
Pete: When Shute uses three dots it means, "Use your own imagination. Conjure the scene up for yourself." (pause) Whenever I see three dots I feel all funny.
