Diane Favero donned a silly hat, a shirt embossed with a picture of herself holding a celebratory wine glass, and the phrase "Grandma's Gone Wild Birthday Bash" -- and then did her best to show off her zeal.
Her antics caught the attention of the crew at "Let's Make a Deal," and host Wayne Brady shouted out for her to "come on down."
The Clayton resident's appearance on the long-running game show airs at 9 a.m. Wednesday on CBS.
"They kept telling us to be exuberant, be lively," she says of learning what gets you noticed. "We were told to keep moving; don't just sit there like a bump on a log."
The entire experience had been a surprise last August, cooked up by her friend and co-worker at the public works department for Contra Costa County. Favero was told only to pack for hot weather.
For the milestone birthdays, it's become a tradition that Favero and Linda Zimmerman join four other friends on a special celebratory excursion. The television appearance was a 65th birthday gift to Favero, who recalls dancing with Brady at some point during the adventure. .
"She was a nervous wreck. Her heart was pounding 90 miles per hour," says Zimmerman of her friend's reaction to being picked to compete.
"I couldn't believe it. I was nervous and I thought 'oh my God," Favero says of her first time on television.
