Sooty, Sweep and Soo want to open their house as a stately home, so they go to a real stately home for some tips. They take a tour with someone at the stately home and have trouble with a cannon. They decide to invite a few people to come round to their house, but when they mean a few then actually mean 10000 people. Matthew thinks it's a crazy idea, but then when he thinks of all the money they could make he agrees. Sweep thinks he's found Henry VIII's bath water and Matthew ends up drinking it.
