The Penguin taints the ink at the U.S. Mint with Lygerian Sleeping Sickness. As word of the infected money gets out, citizens of Gotham City empty their cash right onto the streets - and into Penguin's pockets. But when Bruce Wayne spreads word of the infected bills worldwide, the Penguin realizes his ill-gotten gain is worthless and threatens a more devilish plot if the warning is not retracted.

Did You Know?


This was Burgess Meredith's final appearance as the Penguin on the series. The character did make a brief cameo in the series' penultimate episode, but an unknown actor played the role, while Meredith appeared uncredited as The Penguin (but not in his actual costume and without his fake nose) in a silent cameo in The Monkees: Monkees Blow Their Minds (1968).

Batman and Robin are, in Batman's own words, "duly deputized officers of the law". It is legally impossible to sue sworn law enforcement officers for false arrest - even if the arrest lacked probable cause, police officers are protected by official immunity. Had Penguin filed a lawsuit, the court would have immediately dismissed it with prejudice. See more »

The Last Penguin Episode
11 August 2018 | by StuOzSee all my reviews

Penguin (Burgess Meredith) makes trouble at the mint.

There is no question that this episode does not compare to the sort of quality we got in season one or even season two. But we are talking about 1966 Batman here, one of TV's most popular shows ever made. One of the biggest cult hits ever! So with that in mind I can partly turn a blind eye to the various flaws in this adventure and just go along with it.

The thing that bothered me more than anything else was the terrible make-up job on Meredith. His big nose never looked right (mainly in close ups) and it was just too fake looking. Perhaps the high definition picture quality was to blame for this?

Some interesting plot points in this episode, I would call it good but not great.
