Economics joke

From Radley Balko's Agitator last year:

Three guys are in a jail cell. They start to talking and find out that they're all gas station owners.

The first one says, "I set my prices at a couple of cents higher than my competitors. I'm in here for price-gouging."

The second one says "I set my prices at a couple of cents lower than my competitors. I'm in here for predatory practices."

The third one says "I set my prices at the same price as my competitors. I'm in here for collusion!"

As Radley says in his wrap up: "It's funny 'cause it's true."
