The Fairly OddParents: Season 3, Episode 27 - ProjectFreeTV

3 - 27: Parent Hoods

While the Turners are on their way to Canada, a look-alike duo of bandits called the Turnbaums switch places with Timmy's parents in order to avoid getting punished, and Timmy is simply unable to wish his parents free, because even if magic is used, it could take years to get them out of jail under the US Legal System. It is up to Timmy to get the bandits captured and his parents freed.
