An elderly couple is vacationing in the West. Sam always wanted a pair of authentic cowboy boots. Seeing some on sale one day, he buys them, wears them home, walking proudly. He walks into their room and says to his wife, "Notice anything different, Bessie?"
Bessie looks him over. "Nope."
Sam says excitedly, "Come on, Bessie, take a good look. Notice anything different about me?"
Bessie looks again. "Nope."
Frustrated, Sam storms off into the bathroom, undresses, and walks back into the room completely naked except for the boots. Again he asks, a little louder this time, "Notice anything different?"
Bessie looks up and down and says, "Sam, what's different? It was hanging down yesterday, it's hanging down today and it will be hanging down tomorrow!"
Furious, Sam yells, "And do you know why its hanging down, Bessie? It's hanging down because it's looking at my new boots!"
Bessie replies, "Should'a bought a hat, Sam!"
Bessie looks him over. "Nope."
Sam says excitedly, "Come on, Bessie, take a good look. Notice anything different about me?"
Bessie looks again. "Nope."
