Another good blonde joke

A stranger was seated next to a blonde on the 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?
