A Tough Old Cowboy

A tough old cowboy told his grandson that if he wanted to live a long life, the secret was to sprinkle a pinch of gun powder on his oatmeal every morning.

The grandson did this religiously to the age of 103. When he died, he left 14 children, 30 grand-children, 45 great-grandchildren, 25 great-great grandchildren, and a 15 foot hole where the crematorium used to be.
