Us Old Folks Understand
An older man goes into the Social Security Office and fills out an application for the benefit. He doesn't have a birth certificate, or an ID to prove his age so he opens his shirt and shows them the gray hair on his chest. They accept that as a proof of his age and eligibility.
He goes home to his wife, shows her the check, and explains to her what has happened. She replies, "Well get back down there, pull down your pants, and see if you can get disability!"
