Not hitting at Blondes this time?

Gentleman on a flight, sits down beside a little Blonde lass of about 12 yr. old,she was sitting there reading her book.
The gent says hello to her,then said can I talk with you for company on the flight,the girl said yes, fine he said what shall we talk about I don't know said the girl, you suggest a topic. he thought! then said what about discussing nuclear and atomic powers, super she said but I must ask you one question ok he replied, the blonde lass said sheep eat grass cows eat grass and horses eat grass can you explain to me why sheep pass little pellets cows pass large pancakes and horses pass something like oranges.and they all eat grass, thats a stinker scratching his head, sorry I don't know little lass.She then said what makes you think you talk about nuclear and atomic powers when you don't know S H I T.
