An elderly couple, Linda and Bob, moved to the country. Bob always wanted a pair of authentic cowboy boots, so, seeing some on sale, he bought them and wore them home. Walking proudly, he sauntered into the kitchen and said to his wife, "Notice anything different about me?" Linda looked him over. "Nope.' Frustrated, Bob stormed off into the bathroom, undressed and walked back into the kitchen completely naked except for the boots. Again he asked Linda, a little louder this time, "Notice anything different NOW?!" Linda looked up and exclaimed, "Bob, what's different? It's hanging down today, it was hanging down yesterday, it'll be hanging down again tomorrow!" Furious, Bob yelled, "AND DO YOU KNOW WHY IT'S HANGING DOWN, Linda?" "Nope," she replied. "IT'S HANGING DOWN, BECAUSE IT'S LOOKING AT MY NEW BOOTS!!!" Without changing her expression, Linda replied, "Shoulda bought a hat, Bob. Shoulda bought a hat."
