A man was pulled over for driving too fast, even though he thought he was driving just fine.

Officer: You were speeding.
Man: No, I wasn't.
Officer:: Yes, you were. I'm giving you a ticket.
Man: But I wasn't speeding.
Officer:: Tell that to the judge! (The officer gives man the ticket.)
Man: Would I get another ticket if I called you a jerk?
Officer:: Yes, you would.
Man: What if I just thought that you were?
Officer:: I can't give you a ticket for what you think.
Man: Fine, I think you're a jerk!
