Motorcycle

Jack: I want to buy a motorcycle
me: You have to be 16
Jack: I saw one in my toy catalog and there was a little boy riding it
me: Well, it's probably very expensive
Jack: Then I'll just buy one online
me: You don't have any money
Jack: But YOU dooooo
me: Not for a motorcycle
Jack: Then I'll just have to drive one out of the store
me: That's stealing and you'll go to jail
Jack: They don't put kids in jail until they're 16

(now how exactly does he know this??)
