The episode opens with a flashback to Ken's botched marriage proposal on Halloween. Now 20 years later, Ken tries to arrange the perfect re-proposal for Allison. Meanwhile at the office, which is decorated for Halloween, Damona and Julie accidentally drug Pat and then take advantage of their boss' suddenly giving mood.

Ken is delighted when a long-time favorite patient/comedian comes in for a checkup. Unfortunately, tests reveal that Dicky’s cancer has come back and he must stay at the hospital, keeping him from performing what was going to be his last stand-up show. But Ken is determined to get Dicky what he wants! Meanwhile, Allison runs into an old-time patient at another therapist’s office, causing her to question her own abilities and friendship with the woman.
