I was just watching the season finale and ozzy is trying to get a cat out from behind a mirror, he grabs an object and his wife sharon exclaims, "ozzy no that's the tickling stick, it's an antique" (motioning to a feather duster that looked like it had multiple types of feathers on it) not really a tickle, but if they have a "tickling stick" who knows what happens when the cameras aren't on
