I’m going to go out on a limb and say it’s the Simpsons writers’ invention, because The Simpsons Archive says nothing about it, and they’re totally obsessive about tracing homages, references and quotes.
Since my own looks at SNPP (I should’ve noted what I’d already covered, I guess…apologies) and googling the phrase came up blank as well, I guess I’ll agree. Seems just like the kind of thing that would’ve been a quote…oh well, I guess if they can write comedy, they can write verse as well.
