"Train Whistle"

A fellow who had spent his whole life in the desert
came to visit a friend. He'd never seen a train or
the tracks they run on.

While standing in the middle of the railroad tracks
one day, he heard this whistle -- Whooee da Whoee! -
- but didn't know what it was.

Predictably, he was hit and thrown to the side of the
tracks. It was only a glancing blow, so he was
fortunate to receive some minor internal injuries,
a few broken bones, and some bruises.

After weeks in the hospital recovering, he was at his
friend's house, attending a party one evening. While
in the kitchen, he suddenly heard the tea kettle
whistling. He grabbed a baseball bat from the nearby
closet and proceeded to batter and bash the tea
kettle into an unrecognizable lump of metal.

His friend, hearing the ruckus, rushed into the kitchen,
saw what had happened, and asked, "Why'd you ruin my
good tea kettle?"

The desert man replied, "Man, you gotta kill these
things when they're small!"
