Ah, yes. You gotta love guest stars, especially when they play their part down to a "T." But, first, to the plot line of this episode. Roland's jealousy of Blanche's ownership of the hotel. Roland doesn't want to switch the method of doing things, but Blanche wishes everyone would check in with her before doing anything concerning funds. I think that this really shows Roland's character, how he can be one of the nicest guys, but yet he doesn't want to lose his "baby," so to speak.
But, I would have to say that by far, the highlight of this episode is Bobcat Goldthwaith's portrayal of the guest of Barbara McCrell's show. Everyone thinks that this guy is a screaming, loud maniac who is a former killer. But, it turns out that he's actually a psychiatrist used for her show. He just plays the part awesomely, as it was making me roll on the floor in laughter.
Finally, I still don't think that Oliver is a character that doesn't need to be there. Other than his presence, this episode was a very good example.
