That's a good one. Especially when the voice-over calls them "punters."

The rule under the newspaper flat on the table - you break your ruler.
Or the swipe the table cloth out from under the dining set ( break the china!)

I can't seem to find the tie the ring on the end of the rope, by dropping it down the rope.
It's simple and NO kid will ever be not fascinated.
