Debt -- Nothing About the Bakken

I am reading Debt: The First 5,000 Years by David Graeber, c. 2011.

Early in the book, a little humor, which some days, along with music, is needed:

I was walking down the street with a friend the other day and a guy with a gun jumps out of an alley and says "stick 'em up."

As I pull out my wallet, I figure, "shouldn't be a total loss."

So I pull out some money, turn to my friend, and say, "Hey, Fred, here's the fifty bucks I owe you."

The robber was so offended he took out a thousand dollars of his own money, forced Fred to lend it to me at gunpoint, and then took it back again.
