Best joke I heard in the last 5 minutes...

A tough old Marine 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 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.
