Two elderly men were sitting on a bench in Scottsdale, Arizona enjoying the warmth. One says, “I bet I can tell you how old you are.”
The other says, “You’re crazy.”
“I guarantee you.”
“Okay, what do I have to do?”
“Pull down your pants.”
“What?”
“You heard me. Pull down your pants.”
The second man finally drops his pants. The first one studies the wrinkles rump for a moment and says, “You’re eighty-one years old.”
“You’re a genius! How can you know my age by looking at my rear end?”
“It’s easy. You told me yesterday.”
