One that one of our flight deck told me!!.........
A woman entered the F/D on a visit whilst in flight. She took one look out of the window and promptly said "Are we moving??" The F/O who was totally gobsmacked by the remark quickly replied "No madam, we take off and then hover in the air until the earth spins to the point we want and then we land!" She actually believed him!!!!!!!!!!!!!! How brainless can some people be! YES ITS TRUE
