 Aunt Rosa needs a lot of help with her new apartment, but the last thing she expects is that she ll get it from her dog, Hector. But that s what happens when Hector displays true talent and is cast for a commercial by an eccentric Italian director (Robert Picardo). Producing the commercial turns out to be a little more adventurous than anyone expected, but the biggest surprise is the amount of math used by interior decorators and people who design and make the sets and models for "Star Trek." A surprise, that is, to everyone but Miss Toliver, whose lesson on apartment architecture really "sets the stage" for this episode.
