Ash Ketchum is the psychopathic freak that controls a bunch of Pokémon. Now Michael Vick went to jail for raising and fighting pit bulls. So tell me again why Ash Ketchum is allowed to run around loose and teach kids how to fight their animals. This can only lead to budgie/parakeet boxing, hamster wrestling and the like, and probably sequels to the movie Fight Club using penguins.
Do not leave the job to PETA or the SPCA. When you see Ash, Just stuff his sorry ass and his irritating voice into one of his Pokéballs and leave him like that. It would be super effective!
