Closest thing I can think of is the cop bundling the hood into the back of the car in The Dark Knight and he says "have a nice trip". Aye, that's fine, that's sarcasm, he will NOT have a nice trip, no one likes getting busted.
But then the cop says "see you next fall".
That makes no sense, even less so when you consider these two things are things American kids say when they help other kids fall over. Trip, fall (like the season), it's all linked.
It's total first draft stream of consciousness writing that somehow made the shoot. The writer's subconscious suggested 'see you next fall', which contextually has one use as a pun, after the perfectly reasonable 'have a nice trip' which has two uses, both sarcastic, but one as a pun and one as irony.
Stupid fucking idiots.
Also, the Marilyn Monroe in Red Dwarf doesn't know how to say "boop boop de boop".
