Hi Jack,
It is possible that the improvised, error ridden, fictionalized, and otherwise distasteful episodes were created all in the same day.
It is not uncommon for 2 or more TV shows to be taped in a single day. For instance, the David Letterman show tapes 2 shows on Mondays, and if memory serves me well, one of Monday shows is aired on the following Friday. They must use some caution not to discuss anything relevant to Monday's news as it will already be 5 days old by the time it airs.
Most game shows will also tape at least 2 shows a day. Contestants are asked to bring several changes of clothes to make it appear as though they are returning to the studio on different days. Taping 2 or more shows in a day is economically advantageous as there are numerous behind-the-scenes people that need to get paid and this maximises their efficiency.
As this Murray resides in Vegas, it is possible that his heretical and fabricated episodes are actually taped on different days as he is able to return to the Pawn Shop much easier than a REAL expert who may need to travel from another city.
Another belief which supports the idea that he taped at least 2 shows in one day, lies with the fact that he was not afforded ample time to study his material and disseminate it accurately. An extra day or two would have allowed him to relay some genuine information. It is obvious that he read his material just minutes before the cameras started rolling which, unfortunately, resulted in the 2 counter-factual and defective episodes we witnessed.
If studied in detail, one could compare all the objects hanging on the walls or in the display cabinets against both episodes and see if there are any changes. If an item was sold after the first episode, the second episodes would show that item missing which would give indication that some time elapsed between the two.
If you notice in my Ball and Chain episode, as I was walking towards the door to exit, the lobby was devoid of anything in my path. A moment later, Chum Lee picked the ball and chain up and walked in the same direction as I did, but now he had to walk around a rack of Chum Lee T-shirts in the middle of the lobby. This indicates that when he dropped the restraint through the glass counter top, it was taped at a different time from when I was there.
