I'm not sure how I feel about Bob coming on the show. I'd love to see Bob again, but I can't help but think that when he appears, there will be a sense of being reminded of what there used to be and what we're not getting anymore. I'm sure they won't ask Bob to host any of the games, as that would make it too evident which areas Drew still needs work in.
The other question is the length of the show. It seems like they'd want to spend at least a full minute with Bob, especially since the ovation will last at least 30 seconds, but if the show already feels rushed lately, how are they going to fit in this extra time with Bob? Play Money Game, Double Prices, Switch, Pick-a-Number, 1 Right Price, and then Double Prices again? Because if they race through Bob's appearance, it feels disrespectful to him, to just have him come in and out to hawk his book.
Although overall, I feel the same way as those who are surprised that Bob's making a live appearance at all. Maybe he really wants to sell his book, but I'd think he would be very displeased with some of the events that have recently happened.
