This woman I knew wrote a recipe that had Farmer John's cheese in it. She said we could get it at the farmer's market stand that specialized in cheeses. I went up and asked for it and got a bag label Parmesan.
I laugh every time I see a container of the cheese in my fridge.
Ah, these are called mondegreens, and there's a million of them. English is probably especially prone to them because of homophones and such. One launched a series of children's books featuring, "Olive, the Other Reindeer". (You know, the one who used to laugh at poor Rudolph.)
The word mondegreen is a tribute to Lady Mondegreen from the poem:
They have killed my Earl of Murray And Lady Mondegreen
which is actually
They have killed my Earl of Murray And laid him on the green.
So, mondegreen is itself a mondegreen, and a tribute to a lady that only existed in the mind of its coiner.
