This year marks the 30th anniversary of Pinky and the Brain, the beloved Animaniacs spin-off that gave the world two of animation’s most unlikely lab partners.

At the heart of the series’ enduring charm is the voice of Rob Paulsen, the endlessly versatile actor who brought the dim-witted yet lovable Pinky to life with his unforgettable “Narf!” catchphrase. But Pinky is only one jewel in Paulsen’s long career behind the microphone.

From his heroic turns as Raphael (and later Donatello) in Teenage Mutant Ninja Turtles, to the wisecracking wit of Yakko Warner in Animaniacs, Paulsen’s voice has become an essential part of the soundtrack to multiple generations’ childhoods. In this interview, he reflects on the legacy of Pinky and the Brain, shares stories from his many other iconic roles, and reminds us why, after decades in the booth, he remains one of animation’s most beloved and prolific performers.
