A father and his son, Bobby, arrive at the local Rugby match and Dad can’t find the tickets.
Dad: “Nip home and see if I left the tickets there. “
Bobby: “No probs, Dad. “
Half an hour later Bobby returns to his dad who is patiently waiting outside the stadium.
Bobby: “Yep, they’re on the kitchen table where you left them. “
