The actor of Todd Thompson that is credited as Bartholomew Slater is incorrect. The actor listed, even though they share a name, is an entirely different person. Also, the actor's date of birth is listed as 1971, which would have only made him 8 or 9 years old when this episode was made. The actor portraying Bart is easily between 17-20 years old.
The poem that Bartholomew chanted at the Wilder door about "Lousy Lizy Jane" came from Laura Ingalls Wilder`s book "Little Town On The Prairie". It is in Chapter 15 called "The School Board`s Visit.
This episode is similar to season 3 episode "bully boys." Towards the end of that episode the children came together to fight a bully. It changed his behavior. The same thing happens in this episode.Afterwards the bully promises to behave in class.
Also possibly a tongue-in-cheek reference to one of Michael Landon's first films "I was a Teenage Werewolf" in 1957.
