Two Guys at Home Depot

Two guys, one old and one young, are pushing their carts around the Home Depot when they accidentally collided.  

The old man looks up at the much younger gentleman, "Sorry about that. I'm looking for my wife, and I guess I wasn't paying attention to where I was going."

The younger man replies, "That's okay. It's a coincidence. I'm looking for my wife, too. I can't find her and I'm getting a little desperate."

The old man asks, "Well, maybe we can help each other. What does your wife look like?”

 "Well, she is in her upper twenties, tall, with red hair, bright blue eyes, long legs," the younger man notes, "And she's also wearing tight white shorts. What does your wife look like?"

The old guy stares off into space for a moment and says, "Just like your’s but forty years ago.”
