3x7 - Suddenly Susan

After a tremor shakes things up at the Gate, the staff rescue from the stalled elevator a shaken Lily, a nonagenarian survivor of the 1906 earthquake who shares her off-the-wall story (told via flashbacks featuring the cast) about Lily's mother, an aspiring singer (Susan); a lovesick busboy (Jack); a fortuneteller (Nana); two cough-drop moguls (Todd and Luis); and Enrico Caruso. This is the kind of lame fantasy episode that usually spells the demise of a sitcom, but it does have a fairly terrific dance sequence.
