Just an awful episode all around. Berle's delivery is so bored and low-key that it just screams, "I'm showing up for my paycheck to burn off the commitment to ABC after they cancelled my variety show!"
Now comes Filler Time!
Filler Scene #1. Mister Freeze ends up being the second villain in S3 to be mentioned without appearing (joining Black Widow who was mentioned in "Wail Of The Siren")
Filler Scene #2. I have to dissent from the defense of Barbara regarding her not telling her father about Louie etc. Even if I grant that she didn't see Louie specifically, she was still a "material witness" to a kidnapping and you would have expected her to have gone through the mug books regarding the henchmen who would have been identified as working for Louie (especially in those suits!) So it's more the fact that Barbara seems to be revealing less than she knows to the authorities that rubbed me the wrong way there.
Filler Scene #3. Thanks for resurrecting my ancient post from another blog regarding the "inside joke" of Barbara's regarding the "previous tenant".

Recycling the no-longer-needed GH sets for Batgirl was the perfect way to give the illusion of something "new" for S3 at little cost in a year when cutting costs was the rage for Dozier (it begs the question though of what they would have had to do for Batgirl changing if GH had not been cancelled! One suspects that maybe we would have seen the more simplistic costume change from the test film with Killer Moth or something along those lines)
Of course the thing that struck me on viewing the episode again before listening to the podcast is, if there is a simple door that provides access to the secret room (that Barbara takes Gus through) then why does Barbara bother to use the revolving door in the first place?? This episode has revealed she's got some Gladys Kravitz style neighbors in the building who've been complaining to the maintenance man because of it, so maybe in the future she should just use the regular door!
And gee, what if someone else looking for a match were to open a drawer and see a sign that says "Instant Batgirl room transformer" or whatever it said??
Even worse. Picture dropping the instant Bat costume pill in a glass of water and suddenly a henchman comes in and grabs it out of his hand because he thinks its Alka-Seltzer and drinks it down!
I remember Percy Helton as the drunken Santa in "Miracle On 34th Street" too. Nobu McCarthy (Lotus) had a number of better TV guest shots over the years, my favorite being the 1976 Christmas episode of "Barney Miller" where she plays a mugging victim that Detective Yemana (Jack Soo) takes an interest in, not realizing that her regular occupation is that of a lady of the streets.
You will be in for a rough ride with Nora Clavicle!

(notwithstanding the presence of henchlady Inga Neilsen, one of the most beautiful women of the 60s)
