A man who had spent his whole life in the desert was visiting a friend. To get to his friend’s house, he needed to cross the train tracks. He’d never seen a train or the tracks they run on before so while crossing 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 minor internal injuries, a few broken bones, and some bruises.
After weeks in the hospital recovering, he’s at his friend’s house attending a party.
While in the kitchen, he hears the teakettle whistling. He grabs a baseball bat from the nearby closet and proceeds to batter and bash the teakettle into an unrecognizable lump of metal.
His friend, hearing the ruckus, rushes into the kitchen, sees what’s happened and asks the desert man, “Why’d you ruin my tea kettle?”
The desert man replies, “Man, these things are no joke, you gotta kill them when they’re small.”
