Johnny (age 8) comes into the house for dinner after playing outside all
afternoon. His parents ask him what he did today. He says that he played
baseball and then he proposed to Betty (age 7) the next door neighbor.
They are going to get married. His parents think this is cute, and they
don't want to make fun of Johnny so they ask Johnny him "How are you and
Betty going to pay for the expenses of being married?" He replies "Well
with the $1 I get each week from you and the $1 she gets from her Mom and
Dad, we should do o.k." His father says "That's fine, but how will you pay
the extra expenses if you and Betty have a baby?" Johnny answers "Well, so
far, we've been lucky..."
