Rugrats

Tired of Angelica being bad to them all the time; the Rugrats find Josh, another friend to play with. It started out okay, but it turns out, however, that he is more meaner than Angelica, going as far as risking their lives with a game called "Pillow" (he swings high and jumps ON the babies). According to Josh, what's "fair" is what he (and later, his fist) decides to be fair.
