"Gray Hair"

A senior citizen decided to visit the social security office to sign up   
for his benefits.  Upon his arrival the clerk asked for proof of his age.   
 When he reached for his wallet the embarrassed man realized he had left   
it home.  After explaining his problem to the clerk, she replied, "Don't   
worry, just open your shirt, and if your chest hair is gray you will   
qualify."  The senior citizen opened up his shirt and was soon signed up   
for his benefits.  Upon arriving home, he related the story to his wife.   
She looked at him, smiled and said, "Too bad you didn't drop your pants.   
You would have qualified for disability too!"
