The next day Johnny tells his story:
"My dad fought in the Vietnam War. His plane was shot down over enemy territory. He jumped out before it crashed with only a case of beer, a machine gun, and a machete. On the way down, he drank the case of beer. Unfortunately, he landed right in the middle of 100 Vietnamese soldiers. He shot 70 with his machine gun. But he ran out of bullets, so he pulled out his machete and killed 20 more. But the blade on his machete broke, so he killed the last ten with his bare hands."
The teacher, silent with shock at the story, asks Johnny what could possibly be the moral to his story.
Johnny replies, "Don't mess with my dad when he's been drinking."
