I wish I could watch this episode again now ("Hair," S4, Ep19), but I guess I'll have to wait until one of my streamers runs it. There's a particular scene towards the end that I won't divulge because Spoilers, but just the same, I burst out laughing merely by remembering it.
Basically, it entails New Christine being blamed by the mean parents at Richie's posh school, blaming her for being his being "Patient Zero" in the new school-wide lice infestation. Without proof, simply by sharing false rumors about her, they've made her feel so dejected that she goes to great lengths to prove them all wrong. Watch to the end - the ending's quite good!
