George visits a therapist to discuss a problem with his ex-girlfriend Susan, but the session is unproductive as first George, and then also the therapist, obsess over the stuck zipper on George's jacket. George convinces Susan to get back together with him by citing the example of Louis Pasteur and his wife. Upon their reconciliation he again feels entrapped by the relationship, so he uses "the pick" to disgust her enough to break up with him again. Kramer confronts Calvin Klein (Nicholas Hormann) to complain about "Ocean", and is instead asked to be an underwear model. In the first advertisement to feature Kramer, his genitals are accidentally exposed.
