I had just popped into a shop and when I came out there was a cop writing a parking ticket.

I said what the fuck are you doing?

He said the car is illegally parked.

I told him he's a pig.

So then he writes another ticket for a bald tyre.

I told him he's likes fucking hitler.

So he then writes another ticket for a defective wiper blade.

I said fuck you and he then gives another ticket for expired tax.

You should have seen the look on his face when the owner of the car showed up.
