When Tom is looking after the kids on his own and trying to talk with Kate on the phone, something hits him in the head. Then he nearly gets hit by a frisbee thrown inside the house. A dart nearly hits him in the foot. He has to hide in the front closet to avoid being hit with silly string by Nigel and Kyle. Then comes the hilarious bit when the boys embed an axe in the door.
When Kate is about to come home, the phone rings and Tom goes to answer it. Nigel and Kyle see him and go "GRRRR!" at him. Tom simply tells them to go and get dressed.
