An elderly couple named Sam and Helen are vacationing in the West. Sam always wanted a pair of authentic cowboy boots and seeing some on sale one day, he buys them, wears them back to the hotel, walking proudly. He walks into their hotel room and says to his wife, "Notice anything different, Helen?"

Helen looks him over, "Nope."

Sam says excitedly, "Come on, Helen, take a good look. Notice anything different about me?"

Helen looks again and again says, "Nope."

Frustrated, Sam storms off into the bathroom, undresses and walks back into the room completely naked except for his boots. Again, he asks, a little louder this time, "Notice anything DIFFERENT?"

Helen looks up and says, "Sam, what's different? It's hanging down today, it was hanging down yesterday and it'll be hanging down again tomorrow."

Furious, Sam yells, "AND DO YOU KNOW WHY IT'S HANGING DOWN, HELEN? IT'S HANGING DOWN BECAUSE IT'S LOOKING AT MY NEW BOOTS!"

To which Helen replies, "Shoulda bought a hat, Sam, shoulda bought a hat."
