Wow, Billy; I was just thinking the same exact thing while watching that episode. A good way to tell would be to watch for what tie Mike Bettes is wearing in the episode (I think he's in studio for every single one) and what night he was wearing that tie on A&B. During the very first episode, he was wearing his Wednesday tie, so I have a feeling the day that it's recorded has either changed since then, or it's recorded on a different day every week. Either way, it must be pretty annoying to disassemble the A&B studio mid-week just to have to re-assemble the set to finish off the week.
