It was "Bob Barker's Fun & Games". My parents went to one back in the late 70's and won a dishwasher. They had to do a "Truth or Consequences" type of balancing plates stunt. They got 9 out of 10 plates balanced and were working on the last one as the clock ran out.
In typical Bob Barker style, "Let's give them the prize!".
The group sponsoring the show had went out and bought the prizes locally so they went to the store and picked up the $150 portable dishwasher. The nice wood-like substance top became just another place to put things on.
