A man and a duck on an airplane

A man and a duck sit next to each other in an airplane. A flight attendant stops by to ask if they want any drinks. The man politely asks for coffee. The duck starts to swear to order an orange juice: “I would like an orange juice, and quick, you ugly cow!”…
The flight attendant is a bit startled as she gets the drinks. She gives the orange juice to the duck, but forget about the man’s coffee…
The man asks again: “Excuse me, but I think you forgot my coffee.”…  The duck adds “And please also bring me an apple juice, you silly monkey, and faster!!”…
Again, the flight attendant is very puzzled by how rude the duck is. She comes back with the apple juice but again forgets about the man’s coffee as she was a bit shaken by the rude duck’s comments…
The man, figuring that perhaps you have to be rude to finally get a drink, asks: “ok, you forgetful and ugly pig, can you get me that coffee now???”… This time the flight attendant can’t take it anymore and asks for the airplane security to escort both the man and the duck. Security opens the exit door and just throws out the man and the duck out of the plane… 
As both the man and the duck are falling down, the duck turns to the man and says: “You know, you have a pretty foul mouth for someone who can’t fly.”
