Smells Like Money

I first ran across the proverb Pecunia non olet (Money doesn't stink) in a book about Aldi.
What I didn't realize until today was that the proverb is also a pun. Pecunia means both "money" and "cattle," and of course, cattle do in fact stink (HT: Liberman).

If you've ever been on a farm with livestock, you may have seen this scene played out:

City Slicker: This farm smells.
Farmer: {Inhale}: Smells like money.

It's nice to know that my Uncle Mike has the same sense of humor as the ancient Romans.
