This has been a great season for Curb, once again – how about Salman Rushdie appearing as himself, last week, to give Larry tips on the unexpected babe magnet appeal of “fatwa sex”? But tonight’s episode promises something even more delicious: Bryan Cranston, guest starring as Larry’s therapist, and dueling with him verbally in a counseling session. Cranston, of course, has worked with David before – on Seinfeld, where Cranston memorably played a dentist.
