- This is the first appearance of Grandma Gladys and Grandpa Vlad.
- Timmy's Mom's parents are revealed in this episode.
- This episode shows that Timmy gets his looks from his maternal grandfather (referencing how he takes more after his mom's side of the family than his dad's side of the family), as Timmy bares a strong resemblance to Vlad.
- Yak in the Box is a parody of Jack in the Box.
- The name of this episode is an obvious reference to Timmy's name, Timmy Turner.
- Ustinkistan fairies can only grant wishes involving turnips.
- Even though Ustinkistan fairies can only grant wishes involving turnips, Cosmo and Wanda are able to poof up normal pajamas when it turns to nighttime.
- If you look carefully at the suitcase, you see the words Bon Scott. Bon Scott was a singer for AC/DC
- Another suitcase trivia piece is the word Fairy on it. It is currently unknown why.
- Ustinkistan looks the same in the present and 50 years ago
- Grandpa Vlad could be a reference to Vlad Plasmius form Danny Phantom, another Butch Hartman show.
- Two traditional Ustinkistan holidays are mentioned: Yaksgiving (parody of Thanksgiving) and Yaksmas (parody of Christmas).
- Timmy's grandparents are similar to Mama Cosma, Cosmo's mom, and Big Daddy, Wanda's dad, in that they don't like who their children married (Mama Cosma doesn't like Wanda, Big Daddy doesn't like Cosmo, and Mrs. Turner's parents don't like Mr. Turner).
- Even though Big Daddy doesn't like that Cosmo's his son-in-law, he seems more willing to put up with him than Vlad and Gladys are willing to put up with their son-in-law and Mama Cosma's willing to put up with Wanda as her daughter-in-law.
- If Timmy wished that his grandparents never came to America, then he shouldn't have been born, unless Timmy's own parents had met in Ustinkistan.
- Mrs. Turner's parents giving their son-in-law sacks full of weasels (at the end they give him a sack of badgers).
- Turnips are constantly seen.
