This man went to the pension authorities to claim old age relief. The staff there did not believe he is that old despite having his date of birth.
Staff: Please sir, can you show us anything that will convince us you are that old?
The man opened his shirt and showed the grey hair on his chest. The staff now believed and granted the relief.
The man went home and narrated what happened at the Social Security office to his wife. The wife being angry because the husband showed his nakedness to the staff asked
Wife: Did you remove your boxer for them to see too?
Man: No
Wife: Why? They would have given you disability relief!
