For whatever reasons, this Batman ep never floated my boat. I mean, it's not terrible, it's just kinda meh, IMO. But your show was good as always.
You guys mentioned all the way back in Gorshin's finale how the season 3 ethos seemed to be to make the Duo, especially Robin, look dumber to make BG look smarter, and that continues apace here. I also have to fault Oscar Rudolph's direction. Robin's line about how 'if Penguin didn't take anything out' of the mint followed by the long pause before Batgirl finishes the line is more awkward than it should've been, and that's on the director.
Kyle again had some good points, especially his observation about Beradino not speaking that much in his role, and also what exactly was Penguin's plan? Tim and Paul were right--the equipment and henchperson names suggest they expect people to discard the $$$, but then why did he feel the need to dump the serum?
Oh, and this is a nitpick, but it bugs me how shows/movies always say 'mint' when paper money is the quarry. Mints make coins, period.
Speaking of Beradino, once someone of his caliber has ANY lines, that usually wouldn't affect his pay. It's my understanding the pay had more to do with how many days he/she was on set.
As for Paul's observation about Burt's crosseyed look, it was reminiscent of the African death bee scene in Londinium. African death bee = Lygerian fruit fly I guess.
I also had the MNF electronic game!
Petaluma was the site of the world arm-wrestling championship.
As for The Batman Radio Show, was Steve Martin singing 'King Tut' the Young brothers' answer to Lesley Gore performing 'California Nights' and 'Maybe Now'?
