B:TB&tB season 2 episode 26 "The Malicious Mr. Mind!" Directed by Michael Chang & Michael Goguen.
This "held cell" shot reminded me of the ones I did when I worked on "Fairly OddParents". Now that I think of it, Tara Strong did voice work on this episode (Tara Strong did the voice of Timmy Turner on Fairly OddParents).
