So the old man, as a favour to his best friend, went to the pet store and talked the owner into letting him use a female parrot for one night for the fee of 40 dollars. He took the female home, put it into the cage with his parrot, covered the cage and went to bed. He was awoken in the middle of the night to the female parrot screaming she was being killed.
He ran out and pulled the cover off the cage. There he saw his male parrot ripping all the feathers off of the female. "What are you doing?" the old man screamed.
The parrot replied, "Are you kidding, for 40 dollars, I at least want the bitch naked!"

Come on, you're gonna stripp off your clothes tonight, it's a deal.
