Yes, people love to laugh at this mythical economist, but seriously, when's the last time you saw a legit $20 bill just lying on the ground? I've never seen this even once in my life. Perhaps this mythical economist is the one having the last laugh.
If you allow for faux currency exchange, keeping your eyes aimed down at a renaissance fairground is pretty much guaranteed to turn up enough food tickets for a turkey leg.
You ask if anyone lost any money. If someone says they did, you follow up with "how much money, and how big were the bills?"
Then they have to know an amount, how many bills, and what denomination.
You can imagine that it's hard to fake, and anyone being genuine will have a pretty good idea of what you're holding.
Once, while eating a pizza with canned mussels, he felt something hard. It turned out there was a pearl in his pizza.

It happens.
1996 (±2 years) in an arcade, actually.
It was really ragged, so much so that the bank wouldn't take it. So I still have it.
But it was neat, finding money just right out there on my own lawn.
Sometimes money literally falls out my pocket when I fumble out a wad of cash while i'm inebriated.
Other times I carelessly leave my wallet somewhere stupid and the money "walks off."
Over the past 2 years, I've probably lost over $1000 this way.
Also, "proof" is a noun. You meant to use verb form "proove". "Proof" as a verb means to "proof-read" (to read with an editorial mindset).
The last one is the best.
