Three gas station owners report for their first day in prison. The prison guard asks one of them, "What are you in for?" He replies, "The government says I charged customers more for my gasoline than other gas stations. I'm in for price gouging."
The guard looks at the second man. "And you?" He answers, "I charged less for my gasoline than everyone else. I'm in for anti-competitive pricing."
The guard looks to the third. "And you?" He shrugs. "I charged the same price for my gasoline as all the other gas stations. I'm in for collusion."
