I see a lot of material about McMansions but have never read a nursery rhyme about such homes. Here is the first I’ve seen:

As I was trading up on spouses, I became a man with SEVEN houses
Each house has seven acres,
Each acre has seven servants,
Each servant makes $7,
Acres, servants, dollars and spouses,
Why are the underclass such grouses?

There is not a whole lot here regarding the specifics of McMansions outside of vague ideas about wealth and seeing such homes as deserved. These are ideas often tied to McMansions but could apply to a broad range of big houses (such as mansions rather than McMansions) or even big-ticket consumption items.

I’m not the one to write such things but I imagine someone could come up with a better nursery rhyme involving McMansions…
