An elderly couple, Ray and Bessie, are "snowbirds" in Texas. Ray had always wanted a pair of authentic Cowboy boots. Seeing some on sale one day, he buys them, and wears them home walking proudly. He walks into the house and says to his wife, "Notice anything different about me?" Bessie looks him over, "Nope."
Frustrated, Ray storms off into the bathroom, undresses, and walks back into the room completely naked except for the cowboy boots. Again, he asks, a little louder this time, "Notice anything DIFFERENT NOW?"
Bessie looks up and says, "Ray, what's so different? It's hanging down today, it was hanging down yesterday, and it'll be hanging down again tomorrow."
Furious, Ray yells, "AND DO YOU KNOW WHY IT IS HANGING DOWN, BESSIE? IT'S HANGING DOWN BECAUSE IT'S LOOKING AT MY NEW BOOTS!!!!!
To which Bessie replies, "Should a bought a hat, Ray. Shoulda bought a hat."
