You know, I haven't seen many of these episodes in years. I didn't even remember just how risque some of this dialog was. I'm not sure that I would have been able to resist Selina's charms, but Batman, well, he's always prepared. The banter between them is inspired, and they do have a good chemistry. I think Green Arrow is right in calling them "flirterers!"
All of the women that have worn the catsuit have had their charms. Maybe not Halle's version, but all the rest are OK. None are Julie Newmar though. The poor deluded creature, she really couldn't ever sway the hammers of justice.
