A Maryland math teacher struck it big on ABC's "Wheel of Fortune," becoming the third person in history to win the $1 million prize.

Sarah Manchester, a middle school teacher from Silver Spring, Maryland, appeared on the long-running television game show during the program's "Teacher Week."

In Wednesday night's episode, which was taped back in May, the 42-year-old educator chose the million-dollar jackpot before she went on to solve a puzzle in the bonus round.

After correctly guessing that the answer to the puzzle was "Loud Laughter," TV host Pat Sajek opened the envelope and said "Can you use a million dollars?"

In response, Manchester covered her mouth in shock and let out a scream.

"Oh, I forgot!" she told Sajak once she realized that she won the grand prize.

She was then joined on stage by her husband, two kids and father as confetti dropped from the ceiling.

"My biggest goal was I wanted to get to the bonus round and win something because I wanted to give them that chance to run out and hug and everyone dance like you see on the show," Manchester said Thursday on "Good Morning America."

According to the Washington Post, Manchester applied to be a contestant on "Wheel of Fortune" while the show was holding tryouts in Northern Virginia last fall. Although she was a huge fan of the legendary game show, she never expected to actually be featured on the show, let alone win $1 million.

"The $1 million grand prize wedge was added to the Wheel in 2008. If a contestant collects the wedge, solves the puzzle and makes it to the Bonus Round without hitting bankrupt, the top $100,000 cash prize is replaced by $1 million on the Bonus Round Wheel," reports CBS DC.
