After forming P.A.P.P. - Parents Against Powerpuffs, Stan and Sandra tell Professor Utonium that the girls MUST stop fighting crime by kicks and punches, as they think this might be impressionable to younger kids. They have issued a contract threatening to sue the Professor if the girls don't obey this. In the end, at the brink of destruction brought forward by the Dooks of Doom the Practices tear up their contract, allowing the girls to save the day once again. After the girls saved the day, it is unknown what happened to the Practices.
- Their name is a pun on the word "Standards and Practices," which is the part of a television network that makes sure that the shows are appropriate.
- Their voice actors (Daran Norris and Susanne Blakeslee) also voice another couple Cosmo and Wanda, as well as Mr. and Mrs. Turner in "The Fairly OddParents!", which starred Tara Strong, the voice of Bubbles, as Timmy Turner.
