A Tough Old Cowboy

A tough old cowboy once counseled his grandson that if he wanted to live a long life, the secret was to sprinkle a pinch of gunpowder on his oatmeal every morning. The grandson did this religiously and lived to the age of 110. He left 4 children, 20 grandchildren, 30 great-grandchildren, 10 great-great grandchildren and a fifty-foot hole where the crematorium used to be.
