A little girl goes to her mother and asks "Mummy do birds have spare parts"
     The mother assures her that "no birds don't have spare parts."
     The little girl returns later and says "Mummy are you sure birds don't have spare parts"
           "Of course I'm sure,why do you think birds have spare parts anyway"
           Little girl says "Because I heard daddy say he's going to screw the arse off the bird next door" 

hmmm!!! I think he's going to need some spares shortly!!
