Driving home after a hard day at work, a man gets pulled over by a cop. His patience is wearing thin.

"Tell me, officer: would it be a crime for me to insult you? Hypothetically speaking, of course - I think the police are wonderful - but in theory, could you arrest me if I said you were a cunt?"

"Yes sir. That would count as disorderly conduct."

"What about if I were just to think it?"

"No sir. You can think whatever you like."

"In that case, I think you're a cunt."
