| A son comes home from the Army. After a few hours, he finally gets to talk to his father alone behind the barn. "So, son, what did the Army teach you?" asked the father. "Well, they taught me how to kill people," said the son. "With what?" asked father. "We used all kinds of things, like guns and knives, but my favorite was the grenade," said the son. "What's a grenade?" asked the father. "Well, I brought one home to show you. You just pull this pin out and throw it as far as you can," said the son. The son proceeded to give a demonstration. Lo and behold, the son throws the grenade on top of the outhouse. KABOOM!!! The outhouse is demolished. All the lumber and everything else lands in a heap in the yard. Grandpa sticks his head out of the pile and says, "Whew, glad I didn't let that one loose in the house!" |
