One of Us (The Adventures of Jimmy Neutron: Boy Genius)

Plot
When a show called The Happy Show Show hypnotizes everyone in Retroville, Jimmy and Cindy must stop it before the whole world becomes happy, mindless zombies.

Why It Rocks

 * 1) Hilarious and memorable quotes, such as "Yeah, Carl?  Where have you been for the last ten years?" and "So, um, what were you doing at Betty Quinlain's house again?".
 * 2) Great plot. The Happy Show Show is pretty creative.
 * 3) This episode shows what toxic fanbases are like, which was impressive for early 2006.
 * 4) Amazing action scenes, notably the scene where Jimmy and Cindy are being chased.
 * 5) Perfectly timed jokes, especially where Cindy is constantly asking what Jimmy did with Betty.
 * 6) Good animation.
 * 7) Brilliant ending.
 * 8) It manages to be creepy, yet funny at the same time.
 * 9) "Don't worry! They can't hide from us forever!"

Bad Qualities

 * 1) It has kind of a weird message.
 * 2) The episode doesn't explain how Cindy lost her karate competition to a "six-year-old beige belt on crutches," especially considering the fact that she single-handedly took down Carl, Sheen, Hugh, Judy, and the episode's villain Grandma Taters?

Reception

 * This episode, along with Vanishing Act, hold a rating of 7.1 out of 100 on IMDB.
