Joke: Soldiers and stupidity

Three soldiers had just gotten out of the Army and decided to celebrate by taking a helicopter ride.

One of the soldiers is eating a banana and says, "I wonder if we'd be able to see it land if I threw the peel out?" Out the peel goes and they all watch it, but don't see it land,

One of the soldiers has a rock and says, "This is bigger, we should be able to see it land." They all watch, but don't see it land.

The last one takes a grenade out of his pocket, pulls the pin and tosses it out the door. "We'll see that when it hits!" They watch, but still nothing.

Walking home they see a little girl crying and ask her, "What's wrong?"

"Well, I was walking and slipped on a banana peel that came from nowhere."

The soldiers explained what happened and are helping the girl home when they see a little boy sitting on the side of the road holding his head. They ask, "What happened?"

The boy said, "I was walking when a rock hit me on the head."

They tell the story again and start to wonder what happened to the grenade. One of them races ahead and sees an old lady laughing hysterically. He asks her, "What's so funny?"

The old lady says, "I just farted and my house blew up!"
