Isn't there a rhyming slang in the UK where the last word in this type of word coupling rhymes with the actual word that was intended. For instance someone would say "Since the lift was out, I had to use the bannanas and pairs". When they mean "I had to use the stairs." Come to think of it "Apples and Pairs" is pro'ly the correct word coupling used for stairs, it was just a wild guess on my part anyway.
