Two strangers are sitting in an adjacent seats in airplane.





One guy says to the other, Lets talk. I hear that the flight will go



faster if you strike up a conversation with your fellow passenger.





The other guy, who had just opened a good book, closes it slowly, takes off



his glasses and asks, What would you like to discuss?





The first guy says, Oh, I dont know; how about Nuclear Power?





The other guy says, OK, that could make for some pretty interesting



conversation. But let me ask you a question first:





A horse, a cow, and a deer all eat the same stuff, but the deer excretes



pellets; the cow, big patties; and the horse, clumps of dried grass. Why is



that?





The first guy says, I dont know.





The other guy says, Oh? Well then, do you really think youre qualified



to discuss Nuclear Power when you dont know shit?
