The same old, same old. They think this time the dentist is the mythical Hercules, even though he's a dentist who I think wants to be the world's strongest man. The kids think he's there for bad reasons, so they try to make him leave, and Howie ends up doing so by telling him since he's so strong he can make the Leaning Tower straight, and he can fill in the Grand Canyon and so on, and then he mysteriously gets a new job in Italy.
At least you kind of learn a thing or two about Greek Mythology. Or at least it can put it in your head to want to find out more about it.
I had some laughs with it. Some of the things these kids say are pretty funny.
