A cowboy told his grandson the secret to a long life.

He said, "You gotta sprinkle a little gunpowder on your oatmeal, see. If you do, you'll live to a nice ripe old age."

So the cowboy did this religiously every day, and sure enough, lived to the nice ripe old age of 96.

When he died he left behind 4 children, 8 grandchildren, 15 great-grandchildren

...and a 16 foot hole in the wall of the crematorium.
