The Man From The Desert...
This fellow who had spent his whole life in the desert comes 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 hears the
whistle, "Whooee Whoee!" but doesn't know what it is.
Predictably, he's hit -- but only a glancing blow -- and is 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 one evening. While in the kitchen, he suddenly hears the tea kettle
whistling. He grabs a baseball bat from the nearby closet and proceeds to
batter and bash the tea kettle into an unrecognizable lump of metal.
His friend, hearing the ruckus, rushes into the kitchen, sees what's
happened, and asks the man from the desert, "Why did you ruin my good tea
kettle?"
The desert man replies, "Man, you gotta kill these things when they're
small!"
