Airing[]
When this episode along with "Helga's Locket" was originally intended to air, on the Rainbow Lines era on September 21, 2008 as re-release, Nickelodeon began airing "Crabby Author/Rich Kid" instead. The network did not catch the mistake until just after this episode began, when they switched to the regularly scheduled "Grudge Match/Polishing Rhonda". After this gaffe, On April 12, 2009 as re-release, the entire half-hour segments was finally aired in full.
