Dr. Katz, Professional Therapist Season 2 Episode 10

A Journey for the Betterment of People

Ben is approached by a "woman plying her trade," and it makes him decide to help people in need. He gets pretty obsessed about the whole thing, brags to Laura, calls Katz a failure, insults a long-time family friend, and finally gives up on the idea of helping people -- all in about three days.
