South Park S8e01 Fun With Weapons
The boys buy Martial Arts weapons from the country fair, and turn into Ninja warriors (complete with Anime-style animation). However, when one of Kenny’s ninja stars gets thrown into Butters’ eye, the boys must do the only logical thing possible, dress Butters up as a dog and take him to the vet. Their parents cannot find out that they were playing with weapons.
I don’t think there is an episode of south park I have laughed at this hard.
I can’t help but remember how my firends and I used to play fight as little boys and this is hilariously similar sans the weaponry.
