This is the kind of joke that makes it legal to have public whippings!!
Two buffaloes were roaming in a field near a road in Yellowstone Park, just grazing and generally minding their own business.
A car full of tourists slowly drove by, and one of the passangers stated rather loudly "those are the nastiest, scroungiest things I have ever seen".
One buffalo looked at the other and said "I think that i just heard a discouraging word".
