 Before any part of the episodes were written, the guests were  interviewed by a crew member, sometimes wearing the Space Ghost  costume made famous by Andy Merrill (qv) in some _"Cartoon Planet"  intros. The interviewer also instructed the guest to address him as  "Space Ghost" to maintain continuity. After an interview was done,  the writing crew went back over it, taking pieces out of context and  out of order, assembling them into the responses to Space Ghost and  the rest of the cast. Most of the shows earlier guests assumed they  were participating in a relatively straightforward interview. As the  series became more popular, however, more and more guests became at  least peripherally familiar with what was going on.
