4. DRY

Dr. Katz on "Dr. Katz, Professional Therapist," voiced by Jonathan Katz (left)

The Squigglevision therapist saw all kinds of famous comics and actors, including Winona Ryder, Julia Louis-Dreyfus, Ray Romano, Kathy Griffin, Conan O'Brien, Lisa Kudrow, and David Mamet, and he listened patiently to their shtick. But Katz was always the star of his show, with his stammer, his round eyes, and his very dry style. He was comforting in his low-key way, and he was particularly dear in the non-therapy scenes with his slacker son, Ben, as he tried to maintain his sedate therapy persona no matter how outrageous Ben was.
