Dr. Katz, Professional Therapist

Katz goes to an open-mic night to sing, play guitar and embarrass Ben.

After a checkup shows that he's a prime candidate for a heart attack, Dr. Katz asks Stanley and Laura to help him shape up.

Dr. Katz worries that he and Ben's mother failed to provide their son with everything he needed to know about the opposite sex.

In the never-ending struggle to help his son grow up, Dr. Katz suggests that if Ben had his own car, jobs--and dates--might naturally follow.
