Father Time! / Apartnership! - S1-E4
Plot hole: Timmy uses his heat vision, that he previously wished for, to win the race for his future dad. But it's revealed later in "Smarty Pants" that if you use a previous wish in a contest, it is magically taken away because it's cheating.
Suggested correction: That is true, that rule was mentioned in a later episode. However in the episode Christmas Every Day, it was revealed that new rules could be added at anytime. So it's possible that the rule simply didn't exist yet. Although, this plot hole may apply to any episode released after "Smarty Pants."
Denzel Crocker: Hey, Turner exploded! That's one less mouth to teach.

Trivia: When Timmy goes to the 80s, just before he arrives in front of Dimmesdale University, the 'Back to the Future' car enters the time stream, only to be replaced by Timmy, Cosmo, and Wanda.
The Big Superhero Wish - S4-E3
Question: I know that Crocker's villain parodies Dr. Octopus and Vicky's villain parodies Wolverine, but who is Francis' villain supposed to be?
Answer: There is no specific character he is parodying, just brute characters that take animal names and costumes, like the Rhino.
