A guy walks into a pet shop and there's an exotic parrot in a cage above the shop owner's front counter.
The parrot sees the guy and says, "Psst. Hey, buddy?"
The guy says, "What?"
The parrot says, "Fuck you."
Guy says, "What?"
Parrot says, "You heard me, you ugly ****: ****. You. And **** your mother, too."
The shop owner hears this, comes running up to the front, grabs the parrot out of the cage, and says, "How many times have I told you not to curse at the customers? You do that again I'm gonna rip your wings off and feed you to the cat, you little ****!" And then puts him back in the cage.
The next day, the same guy comes back to the pet shop. And the parrot sees the guy. The parrot says, "Psst. Hey, buddy?"
The guy says, "What??"
And the parrot says, "....You know."
