Socializing tonight and met a guy who was a contestant on "I'm Telling" when he was 7 years old. For those who are interested in how these things worked....
The contestants didn't actually get any of the prizes in the Pick-a-Prize Arcade. They were told in the contestant briefing that they'd be getting a toy store gift certificate for the cash equivalent of whatever prizes they won. In fact, the contestant coordinator even said, "Don't even think about the prizes you want or the prizes you think your brother would want. Just pick what you think are the most expensive prizes because we can give you a bigger gift certificate that way."
Side note, from the same conversation:
Him: "Also, a few years earlier, my parents were contestants on a show called '3's a Crowd."
Me: "Are they still married?"
Him: (Laughs) "Oh, god, no."
