There a guy on an airplane with a duck sitting next to him and the guy is smoking a cigar.The stewardess comes by and says she "this is a no smoking flight get rid of that." So the guy rolls down the window and throws out the cigar(don't ask me how).
After a while the stewardess comes by and says "what is that?" The guy replies "this is my pet duck" and the stewardess tells him no ducks are allowed in the airplane with out a cage and are supposed to be carried down in the bin. The guy says "well what do you want me to do about it?" The stewardess says "get rid of it". So he rolls down the window(I know) and throws his pet sadly out. After a while he looks out on the wing....... and guess who he sees???
Yes the duck...... and what does he have in his mouth?.............
