A 7 year old boy is having dinner with his parents when suddenly he announces that me and Jane next door are getting married.
"Oh" says the mother amused, "How old is Jane?.
"Six", says the boy.
"What are you going to do for money?" asks the father.
The boy says, "I get 5 dollars a week allowance and Jane gets 3 dollars. Together we'll be okay."
"What will you do if you have children?" asks the father.
The boy says, "Well, so far we've been lucky."
