The Texan, the Californian, and the Arizonan
A Texan, a Californian, and an Arizonan are out riding horses. The Texan pulls out an expensive bottle of whiskey, takes a long swig, then another, and suddenly throws it into the air, pulls out his gun and shoots the bottle in midair.
The Californian looks at him and says, "What are you doing? That was a perfectly good bottle of whiskey!"
The Texan says, "In Texas, there's plenty of whiskey and bottles are cheap."
A while later, not wanting to be outdone, the Californian pulls out a bottle of champagne, takes a few sips, throws the champagne into the air, pulls out his gun and shoots it in midair.
The Arizonan can't believe this and says, "What the heck did you do that for??? That was an expensive bottle of champagne!"
The Californian says "In California, there's plenty of champagne and bottles are cheap."
So a while later, the Arizonan pulls out a bottle of tequila. He opens it, takes a sip, takes another sip, then chugs the rest. He then puts the bottle back in his saddlebag, pulls out his gun, turns around and shoots the Californian.
The Texan, shocked, says, "Why the hell did you do that?!"
The Arizonan replied, "In Arizona we have plenty of Californians, and bottles are worth a nickel."
