>>1 That was my reaction to that episode as well. Eventually I just settled down with "hilariously uncomfortable". I was laughing my ass off while squirming in my seat simultaniously. It was great.
As for the most disturbing scene I've ever seen in anime? Probably the instrumentality scene in End of Evangelion. It's much less disturbing now, but the first time watching it was... an interesting experience. Giant Naked Rei and her creepy sunken eyes, people exploding into Tang, Rei's body decomposing and rotting apart like wet tissue (twice!), the MP Evas vomiting out multiple Rei faces, forehead vaginas with eyes in them, giant red needles plunging into said vagina eyes, Giant Naked Kaworu's torso emerging from Giant Naked Rei's body... you get the picture...
