Pokémon parody wasn't much better. It involves Pikachu and Squirtle babbling nonsensically at each other in
Pokémon Speak for several seconds until Squirtle gets fed up and starts ranting about how stupid the show is, yelling at viewers to read a book or something. The anime never does this; on the rare occasion that conversations between Pokemon are focused on (the main characters are, in fact humans, and the focus is on them), it's typically arranged so that it's possible to guess at what they're saying based on context, body language, and facial expressions. Subtitles were used in the early episode "Island of the Giant Pokemon", since the intended dialogue was too specific for that.
Another Pokemon parody focuses on what goes on inside of Pikachu's pokeball, despite the fact that Ash's Pikachu almost never goes inside its pokeball because it doesn't like it. Also, the sketch ends with Ash pitting his Pikachu against a Charizard, which causes Pikachu to sigh in resignation to defeat, thinking Ash must be an idiot to put him up against a Charizard. While Pikachu is a lower-tier Pokemon than Charizard, Charizard is part flying type and is
doubly vulnerable to electric attacks, so even a regular Pikachu would have a type advantage over Charizard. This, combined with the fact that Ash's Pikachu is absurdly powerful and has held its ground against a Dragonite and a Regice(among other legendaries and psuedo-legendaries) makes this joke grating for anyone familiar with the series to watch.
An episode mocking iCarly consistently poked fun at how morbidly obese Gibby is, despite the fact that the actor had lost the weight years ago.
