Bob went to Medical Insurance to apply for his
pension.
The woman behind the bench asked for his
driving license to verify his age, but he had left
his wallet home.
He said to her that he had to go home and return
later.
The woman said: "Unbuckle your shirt."
And so he did, revealing his curly, gray hair of his
chest.
"These gray hair is quite a nice proof for me,"
she said and continued with his application form.
When Bob went home, he said to his wife what
had happened.
The wife said to him "You should have taken your
pants off,"
"Why?" asked the man
"Maybe you would have taken disability pension
too!" replied the wife
What does this woman mean??
