Another Treasure Hunt question: how did they always wind up with female contestants when there were both genders in the "studio audience"?
The "how" is easy. They gave the 10 wrapped boxes to 10 females every half.
I now recall the Geoff's safety bit, but similar to BillCullen1, I just assumed Chuck wanted the emotion they figured females always exhibited. Unlike LMAD and Price who built their shows around the contestants, prizes and the games, there was no game to Treasure Hunt. It was just "pick-a-box." So, it relied on the prizes, skits, Geoff and crew's delivery of those skits and, most importantly, the reaction of the contestant. While the men on TPIR and LMAD would love a living room, dining room or a fur coat to give to their wives, they weren't always as expressive as the females that could win and use those items more. As was also stated, it also allowed them to tailor skits around women. Also, let's not pretend advertisers didn't still covet the housewife demographic back then. I bet they were awfully more likely to tune in if they constantly saw women participating and think, "I'm watching this because that could be me up there one day." It was a ploy and given it's Chuck Barris, I'm not surprised.
