An unintentionally insensitive remark by little Ritchie (Larry Mathews) has Sally (Rose Marie) regretting the fact that she is still unmarried. Even so, Sally insists upon celebrating her birthday alone, and refuses to let Rob (Dick Van Dyke) and Buddy (Morey Amsterdam) try to cheer her up. The situation takes on a new dimension when Sally informs her co-workers that she intends to spend her birthday with an old school chum named Leo Fassbinder. Convinced that she has invented this "chum" (what a ridiculous moniker!), Rob and Buddy secretly scheme to pay her a surprise visit that evening. It turns out, however, that Leo is quite real -- and, sad to say, a major disappointment for the fragile Sally.
