The Adam/Eve/Blair storyline on DS was not "campy" - at least not intentionally. However, it has been interpreted as such by some viewers. At this point in the series, Dan Curtis and the writers were trying to attain a new level of strangeness by upping the ante, so to speak. The over-the- top nature of these storylines, coupled with the the larger than life performances of certain actors, have lead some to label this segment of the series as camp (incorrectly so, IMO). If you watch some of the Universal horror films, the stories are very grandiose and the acting can be way over the top. I would not call these films campy though. The genre we are dealing with involves an exaggeration of the natural. This is sometimes interpreted (incorrectly IMO) as camp. The 60s Batman show is campy. DS is not. I will concede that as the show progesses, it increasingly relies on a willing suspension of disbelief on the part of the viewer.
That being said, the sequence you described is still pretty amusing.
