Sam and Bessie are in their 80's and Sam always wanted an expensive pair of alligator shoes. Seeing them on sale one day, he purchases them and comes home, asking Bessie, "So, do you notice anything different about me?"

Bessie responds, "What's different? It's the same shirt you wore yesterday and the same pants,"

Frustrated, Sam goes into the bathroom, undresses and comes out naked, just wearing the new shoes. Again he asks, "So, Bessie, do you notice anything different?"

Bessie again responds, "What's different, Sam? It's hanging down today; it was hanging down yesterday and will be hanging down tomorrow,"

Angrily Sam yells, "Do you know WHY it's hanging down? Because it's looking at my new shoes! THAT's why it's hanging down!"

Bessie replies, "You should have bought a new hat!"
