I love the fourth season of the show; a lot of changes occurred during that year.
Tidbits:
-Second playing of Dice Game; always interesting to see it with the original rules.
-Almost perfect playing of Shell Game; still, always exciting when the $500 is brought to the table.
-The normal beeps were used on the Big Wheel, but would soon go away and not return until a few years later.
-Dig We Must is used in the SCSD. I didn't think it was used in Season 4 at all.
-The green podium is still used for the top winner; although Steve speculated once that the podiums may not have had specific positions until Season 5.
-An early $1 bid. John stated waaaaayyy back in 2008 that the first one occurred on January 19, 1976, which would have been taped around November, 1975. Carlos also said in the same thread that he saw one occur on a 1974 episode, but as far as I know, he hasn't posted the clip. I wonder if he still has it on tape...
