Prove It, Old Timer

Old Pa Jones was getting ready to go into town to apply for Social Security. Ma says, "You don't have a birth certificate. How are you gonna prove your age?" "Now don't you worry, Ma," says Pa, and he leaves for town. Old Pa returns home a few hours later and reports that he'll be getting the first check in about three weeks.

"So, how'd ya prove your age?" asks Ma.

"Easy," says Pa, smiling. "I just unbuttoned my shirt and showed 'em all the gray hairs on my chest."

"Well, while you were at it," scolds Ma, "why didn't you drop your pants and apply for disability?"
