Suppose Bob had retired any time before March of 2006, or suppose Peter Tomarken hadn't died when Bob did retire? What would the show have been like with Mr. Tomarken at the helm? Would he have ever even been on that plane (thus still be alive today) had he gotten the TPiR job? Might we have had a "Press Your Luck" reunion had Rod also been alive at that point, and if so how long would it have lasted?
Suppose all four "classic" models (Dian, Holly, Kathleen, and of course Janice) had still been with the show when Bob retired; the circumstances leading to their departures not occurred? Might they still be on the show today, or would they still have been replaced by younger models (not necessarily who's there now) eventually?
Suppose Bruce Forsyth had come back across the pond (he having previously hosted "Bruce Forsyth's Hot Streak" stateside) to take over from Bob when Bob retired? For what it's worth when "Hot Streak" was cancelled he was offered the job of hosting the late '80s version of "Card Sharks".
