With just one letter left, Kevin thought he had this puzzle and the prize money in the bag. That is until, he made a racy mistake that turned the Tennessee Williams classic into an X-rated story.

With "A STREETCAR NA_MED DESIRE" on the board, Kevin made a comical misstep by calling a "K".

Naturally, the literary novel that has been taught in schools isn't called "A Streetcar Naked Desire."

Of course the next contestant Lisa, was happy to guess the "M" and take the win for the puzzle.

"And although you got the right answer, I'd rather see Kevin's play, but that's just me." host Pat Sajak said to Lisa, laughing.

After that mistake, he will definitely be screaming "STELLLLLAAAA!" in his sleep.
