A man who had spent his whole life in the desert visited a friend.

He'd never seen a train or the tracks they run on. While standing in the middle
of the railroad tracks, he heard a whistle, but didn't know what it was.

Predictably, he was hit and thrown to the side of the tracks, with some internal
injuries, a few broken bones, and some bruises.

After months in the hospital recovering, he was at his friend's house attending
a party.

While in the kitchen, he suddenly heard the teakettle whistling.

Grabbing a baseball bat from the nearby closet, he bashed the teakettle into an
unrecognizable lump of metal.

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

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