Lou is closing in on fifty and today is his birthday. Mary can't stand the thought of the now-separated Lou celebrating his birthday all alone, so she arranges a surprise party for him. That evening, she invites Lou over for a drink and the doorbell rings just as he tells her how much he appreciated her not throwing an office party for him that afternoon.

Phyllis, who has gotten her real estate license, persuades Lou to sell his house. However, Lou hasn't really made up his mind whether he wants to move.
