S1·E11 Instant Dharma

Dharma's parents arrive for their weekly yoga class only to find Dharma in tears because all her other students have deserted her for the popular self-defense class across the hall. Greg's efforts to cheer her up only get them evicted from Kitty's operatic fund raising evening. Clearing out her locker, Dharma curiously wanders into the self-defense class that turns out to be run by a wacky woman named Spyder, who is promoting herself with alarmist flyers about a massive increase in crime in the neighborhood. When Dharma protests that this is a lie, Spyder intimidates her physically, then invades a depressed Dharma's nightmare about breaking her non-violent principles and retaliating. When Dharma does attempt to remonstrate with Spyder, both she and Greg get their butts kicked.
