If you found a random bag full of money what would you do with it?

Move to Ireland and buy a guitar.

I would eat it.

Poor people don't carry around bags of money, so I'd keep it.

Specifically id call the non-emergency line and sit with the cash till an officer came to collect it

Idk. What if it belonged to an elderly person then i would feel bad. Or someone who needed the money to pay their rent.

I would give it to my investment counselor Donald J. Trump and ask him to invest it wisely on my behalf since I'm not as business savvy as he is.

Depends on the denomination. There was a movie "A Simple Plan" that dealt with that situation. Ten percent of the $100 bills were recorded of "found" mob money making spending it impossible.

It might be a setup, so I would look around carefully first, then take it.
Now what to do with it after is the question. I like to think it's a little old lady that lost it and she is frantic to get it back so would wait for a post, or poster or something. On the other hand it might be drug money in which case it is free as long as you don't get caught with it then you would be dead.
Some people take it to the cops and they have a nice dinner with it. Doubt I would do that.

I don't know. But if you turn it into the cops you can kiss it goodby.
