A after retiring, I went to the social security office to apply for  Social Security, the woman behind the counter asked me for my driver's  license to verify my age. 

I looked in my pockets and realized I had left my wallet at home. I told the woman that I was very sorry but I seemed to have left my wallet at home. "I will have to go home and come back later." 

The woman says, "Unbutton your shirt." 

So I opened my shirt revealing my curly silver hair. 

She says, "That silver hair on your chest is proof enough for me" and she processed my Social Security application. 

When I got home, I excitedly told my wife about my experience at the social security office. 

She says, "You should have dropped your pants. You might have gotten disability too."
