A stranger was seated next to a blonde on an airplane when the stranger turned to her and said, 'Let's talk. I've heard that flights go quicker if you strike up a conversation with your fellow passenger.'

The blonde, who had just opened her book, closed it slowly and said to the stranger, 'What would you like to talk about?'
'Oh, I don't know,' said the stranger. 'How about nuclear power?' and he smiles.

OK, ' she said. 'That could be an interesting topic. But let me ask you a question first. A horse, a cow and a deer all eat the same stuff - grass. Yet a deer excretes little pellets, while a cow turns out a flat patty, and a horse produces clumps of dried grass. Why do you suppose that is?'
The stranger, visibly surprised by the blonde's intelligence, thinks about it and says, 'Hmmm, I have no idea.'

To which the blonde replies, 'Do you really feel qualified to discuss nuclear power when you don't know shit?
