Dr. Kirk Langstrom and Penguin in “Pets”

So that's the wretched device which controls me. Its frequency must have triggered my echolocation bat-hearing and reactivated dormant traces of the serum in my system, transforming me into Man-Bat!

...Yeah, whatever. So I just gotta flip this puppy on to turn nerd-guy back into Man-Bat?

I shall allow you to live, Penguin, if you hand it to me now.

Hand what to you, huh, this? This?! [waves it at Langstrom mockingly and knocks him back with his umbrella, laughing]

Then be sure you never lose it. For the first opportunity I get, I shall clip your flightless wings.
