The show is based on Andy Griffiths' children's series of Just! books (which were illustrated by Terry Denton), although many episodes are not directly based on the books. Changes from the books to the TV series include Andy's last name, which was originally that of his creator, and other minor name changes, such as Lori's name being Lisa in the books. The book series was based on the early life of Andy Griffiths. It was originally an interactive Flash movie with completely different voice actors and a promotion for Fox Kids. A TV adaptation was announced by CinéGroupe on March 23, 2001 for broadcast on Teletoon and Fox Family later on in the year. The main production of the series moved to Canada in season 2, which was co produced with the French studio SIP Animation (itself split from Saban Entertainment) and in association with German channel Super RTL. All the voice cast had to be replaced with this move with the exception of Andy Larkin's voice actor Ian James Corlett, as he was Canadian himself. As Saban Entertainment had by then been acquired by Disney, distribution of this season was handled by Disney subsidiary Buena Vista International Television. In September 2003, the voice of Lori in Season 2, Jaclyn Linetsky, who also played the title character on Caillou, Meg in Mega Babies, and Megan O’ Connor in 15/Love, died in a traffic collision during production. She had managed to finish all of Season 2 prior to her death, but for the following season she was replaced by Eleanor Noble. The episode "Nurse Jen" was dedicated in her memory. Season 3 was a collaboration between CinéGroupe and Super RTL, and distributed by the production company directly. The whole series was later added to CinéGroupe distribution partner HG Distribution's catalogue.

In the United States, the series was first shown on September 22, 2001 on Fox Family Channel, later ABC Family. On January 17, 2005, it premiered on Toon Disney, which also had rights to the second but not the third season.
