This is the first episode in Season 1, and is considered the first episode of the main series.
The other kid actually goes to the same school as Timmy goes, although he is only seen in background shots.
When Timmy said it was 6:04 Vicky said it was 9:04 on the east coast which is 3 hours apart, that gives the viewers a hint they live in California (which was revealed in Christmas Every Day and Fairy Idol).
This is the first time Timmy sees his Mom and Dad kiss.
Although this is the first appearance of Chester and A.J., their names are not revealed until the accompanying episode "Power Mad".
Toy Story - The kid that the fairy messenger showed to Cosmo and Wanda is similar to Sid, due to his appearance and his toy abusing personality.
Something breaking or dying whenever someone says Vicky's name.
The word creep or creepy being said after Timmy wishes to be an adult.
Characters having a shaving problem, resulting in them injuring themselves.
When Vicky sees Timmy as an adult, she becomes shocked, blows a whistle and uses karate moves on Timmy.
It is unknown how the mean kid knew about fairy godparents.
After Timmy is transformed into an adult, Cosmo and Wanda's reaction was "ewwww", but if you watch their mouths carefully, they are out of sync with the words and they seem to be saying something else.
It is unknown how did Timmy get a car. It is impossible because Mr. and Mrs. Turner took their car to the movies.
After Timmy heard Francis bullying Chester, he said "This looks like a job for..." then Cosmo and Wanda continued Timmy's phrase "...older Timmy", but if one looks closely at the movement of Wanda's mouth, there is no teeth shown. But in later episodes, Wanda's teeth always appear when she talks.
It is unknown why Timmy did not forgot that he even had fairies because according to Channel Chasers, when Timmy was 18, he did not realize who Cosmo and Wanda were.
It could be possible that this does not apply here since Timmy did not age himself with an actual aging device (The magic televion remotes aged people if they pressed the fast forward button on the remotes).
The adult Timmy from Channel Chasers looks different from the adult Timmy in this episode.
It might be because this Timmy was older than the one from Channel Chasers.
It could be due to the fact he aged himself by wishing and not via aging devices.
At school during the brief football game, Timmy is wearing a heavily-padded football uniform and a helmet with a small portion of his hair can be seen sticking out. However, after being assigned the position of being the ball, the scene cuts to one of the football players picking up Timmy, and the hair sticking out is gone. However, after the football player tosses Timmy, his hair can be seen sticking out again.
This episode suggests that Fairy Conventions are a place where the fairies meet and discuss things. However, in Cosmo Con, it is show to be more like a Comic Con.
It is unknown why Cosmo and Wanda did not go away because the other prisoners saw them.
It is possible that the fairies are safe because the prisoners would most likely not be believed.
