There were two different goldfish playing the role of Myra. They were named Mary Kate and Ashley.
The complete text of Jill's "Missing" flier is "MISSING! Lost goldfish in park during Lunchtime on Tuesday. Responds to the name Myra. Last seen in her bowl. If you've seen her, please call 555-2479. JILL"
Except for Jill, all of the names listed in the apartment directory are members of the cast and crew.
