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 unbilled as The Penguin in a silent cameo in the penultimate episode of THE MONKEES, "Monkees Blow Their Minds."

Burgess Meredith is guaranteed a clean getaway
25 April 2016 | by See all my reviews

"Penguin's Clean Sweep" marked the final appearance of Burgess Meredith's Penguin on the series, certainly better served this last season than Cesar Romero's Joker (Meredith actually does one last cameo as The Penguin in THE MONKEES "Monkees Blow Their Minds"). With henchmen named Dustbag and Pushbroom, and Monique Van Vooren as Miss Clean, the overstuffed bird intends to contaminate all the money in Gotham City with Lygerian Sleeping Sickness, using his collection of Lygerian fruit flies to accomplish the task, thus sweeping up every piece of green paper dumped on the sidewalk. Unfortunately, Bruce Wayne's influence leaves Penguin with millions in worthless paper, no bank or merchant in the world willing to deal with his ill gotten gains. Unbilled cameos this time include John Vivyan (MR. LUCKY) as a bank manager, and former MLB player John Beradino, fittingly cast as a doctor.
