In case you're puzzled about why you've never seen these scenes, they come from the GinRei Specials, a series of OAVs (three, so far) which were released in-between the Giant Robo episodes. They're basically parody side-stories; the first one is fairly sane, but the second is...mutant. Hysterically funny, though, if you know the show well. Most of these captures are from the second one. I've finally seen the third one; IMHO, it's not as enjoyable as the other two. For one thing, it's serious--for me, the whole appeal of the specials is that they're comic. But it is an interesting side-story.
