Iron horse

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 teapot whistling. He grabs a baseball bat from the nearby closet and proceeds to batter and bash the teapot into an unrecognizable lump of metal. His friend, hearing the noise, rushes into the kitchen, sees what's happened and asks the Apache guy, "Why'd you bust up my teapot?" The desert man replies, "Shii' kiis', you gotta kill these things when they're small."
