A congressman was seated next to a little girl on the airplane leaving from DALLAS when he 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 little girl, who had just opened her book, closed it slowly and said to the total stranger: 'What would you like to talk about?'
'Oh, I don't know,' said the congressman. 'How about global warming or universal health care', and he smiles smugly.
'OK,' she said. 'Those could be interesting topics. 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 Congressman, visibly surprised by the little girl's intelligence, thinks about it and says, 'Hmmm, I have no idea.'
To which the little girl replies, 'Do you really feel qualified to discuss global warming or universal health care when you don't know shit?'
