MARSHALL TWP, Alleg. Co. — A former cashier from the Seven Fields Giant Eagle will compete on the nationally syndicated TV game show “Jeopardy” Tuesday evening.

Shannon Crock, who lives just over Butler County's southern border in Marshall Township, was not allowed to reveal how she did on the show, which airs locally at 7 p.m. on WPXI-TV.

Crock explained an entire week of shows are filmed at the quiz show's studio in Los Angeles on Tuesday, and the next week another five shows are taped on Wednesday.

Crock, who graduated from North Allegheny High School in 2004, said she took the online “Jeopardy” test a few times before being contacted by the show's producers to travel to New York Feb. 8 for an audition.

There, Crock said she tested in a group setting before being interviewed and competing in a mock game of “Jeopardy.”

When she passed that test, her name was placed into a pool of successful contestants, and she was told the show's producers would call her for a taping in Hollywood.

She was asked by “Jeopardy” personnel to compete in a game being taped March 8, so she and a friend bought airline tickets for the trip to L.A.

Crock said contestants pay their own way to Los Angeles when they are called to compete, but those costs are covered because third-place finishers get a $1,000 prize and second place takes home $2,000.

Contestants are told to show up at the studio a few hours early, where they are instructed on what to do and not to do.

“Everyone is really super friendly,” Crock said of the show's staff.

One directive given to contestants is to dress “business casual,” she said.

“The whole show is pretty structured,” Crock said.

Regarding the short chat with longtime “Jeopardy” host Alex Trebek after the first commercial break, Crock said she talked about her hobby of participating in costume play at anime conventions. She talked with Trebeck about the swords involved in that hobby.

“He's got a dry humor,” Crock said. “During the commercial breaks, he does a question-and-answer with the audience.”

She admits to being nervous about taping the show, but she and the other contestants were reassured by the “Jeopardy” staff.

“They said 'You have already done really amazing just getting this far, so enjoy yourself,'” Crock recalled.

At the time of the taping, Crock was working as a cashier at the Giant Eagle supermarket in Seven Fields. She is now employed as an insurance verification specialist in Sewickley.

Lynn Crock, Shannon's mother, said she was excited but not surprised that her daughter would compete on “Jeopardy.”

“She's always been very bright and had a good memory,” she said. “She could read by herself when she was 2.”

She and Shannon will watch the show together Tuesday night.

“It's exciting and I'm just eager to watch it,” the elder Crock said.

Shannon Crock said she has always wanted to compete on the quiz show.

“I just really like 'Jeopardy,'” she said.

The format of the show was also somewhat familiar to Shannon.

“I was on the Quiz Bowl team at (North Allegheny High School),” she said.

Crock earned a bachelor's degree in biochemistry from Case Western Reserve in Cleveland and a master's degree in forensic science from the University of Alabama in Birmingham.

While she couldn't divulge her success or failure on show, Crock said the experience was a once-in-a-lifetime thrill.

“I really, really enjoyed it,” she said. “It was a lot of fun.”
