Why you should get married?

A conversation, between John and his friend Ruby, I listened in on as we were driving.

John "I am going to marry Sammy"

Ruby "I am not going to get married, I am just going to stay a kid forever"

After much thought John replies "I have to get married because I have to eat."

Thus I see that through John's eyes my role as a wife is to feed my husband, I suppose I should work on that one, ehh?
