For instance, the quote from Douglas Adams:
“In those days spirits were brave, the stakes were high, men were real men, women were real women and small furry creatures from Alpha Centauri were real small furry creatures from Alpha Centauri.”
Where he takes a common phrase ([in the past] men were real men, women were real women) and extends it to small furry creatures from Alpha Centauri, thus making the list seem absurd by appending an element to it that jars with our previous impression.
Is there a word or phrase (ancient or modern!) to describe the method of making a list humorous by including an element that fits the pattern of the others syntactically ("X were real X") but not thematically?
I was thinking of "epizeuxis", but that doesn't seem right, as I'm thinking of when a pattern is repeated, not a single word or phrase.
