A Parrot and a Donkey are on a plane, sitting in coach. The Parrot buzzes the stewardess, and she comes over. She asks him: "Can I help you with something?", and he replies" Nahhh..I was just fucking around!" and starts laughing. The Donkey thinks that's hilarious and laughs with him.
After a while the Donkey feels like imitating the Parrot's prank, so he buzzes the stewardess. She comes over and asks him: "Can I help you with something?", and the Donkey replies "Nahh..I was just fucking around too!" and starts laughing, and gets joined by the Parrot.
The Stewardess, annoyed at those two imbeciles, goes to the Captain and tells him that she has a parrot and a donkey who keep buzzing her for the hell of it. The captain instructs her to throw them both out of the plane, which with the help of the rest of the in-flight crew, she succeeds in doing.
As they are plummeting towards earth, a terrified Donkey asks the Parrot: "Now what do we do?"
The Parrot calmly responds: "It's no big deal. Now we fly!"
The Donkey replies with frustration: "But I am a donkey, I can't fly!"
To which the Parrot deadpans: "So, if you can't fly, what the hell are you doing fucking around?"
