A tough old Montana cowboy once told his grandson that, if he wanted to live a long life, the secret was to sprinkle a little gunpowder on his oatmeal every morning. The grandson did this religiously, and he lived to the age of 93. When he died he left 14 children, 28 grandchildren, 35 great-grandchildren ... and a 15-foot hole in the wall of the crematorium.
