Attempting to solve the puzzle “frozen concoction,” Davidson threw in the indefinite article “a” at the beginning of his answer, a technical error that meant his opponent Carol got to solve and win the prize.

“Chris knows what he did, which is why he went back,” host Pat Sajak explained. “He threw in that article. He threw in the “A” in front of it, and we can’t accept it. Just the way it goes. It’s just one of the rules, and we gotta go by ’em, and Carol ends up getting the trip to Puerto Rico.”

Davidson ended up making it to the bonus round, and though he wasn’t able to correctly answer the puzzle, he still walked away with an impressive $13,900.
