I am wondering if there is any name, or well-known example, for a humoristic construct that I particularly enjoy. It is exemplified in this monolog from Pierre Desproges, directed at a woman he was interviewing for a radio off:
Lady, you're a beautiful flower — can I call you a flower? [...]
(later in the interview) You're a cute white cloud in blue summer sky — can I call you a white cloud?
(some more such lines throughout his monolog, you get the idea)
(and it ends with:) You're gorgeous as a cab — can I call you a cab?
I'm not even sure there is a specific term for this build-up and final twist. It's sort of related to a syllepsis (which would be can I call you beautiful and a cab?), but delayed in time. Is there a name for this construct? Do you know of famous examples in English?
(I do apologise because translation of humor is necessarily weak, and is not my forte. I do it because I don't know any good example in English.)
