Three kids are talking at school... The first one says: ""my dad is a formula one driver; he is super fast!"" The second one answers: ""Really? My dad is a pilot, and with his jet he is even faster than your dad!"" They both turn to the last kid. He puts down his cookie, and tells the others: ""My dad is so fast, his timetable says he finishes work at 6, but he's always home by 5"". The two other kids are amazed, and they ask where his dad works. ""He's a state employee"".
