In a shocking twist to tonight's "Dancing With the Stars" competition, all of the couples are safe from elimination.

"Everyone take a deep breath and rest up," host Tom Bergeron announced tonight, explaining the show decided to "discard all of the viewer votes and not eliminate anyone," due to technical problems last week.

The problems resulted in votes accidentally being cast to the wrong couples, which proved fortunate for both Jack Osbourne and Bill Engvall, who were two of the lowest scorers tonight, and the last to be announced as "safe" for the unforeseen technical problems.

"Emma, I could see you tearing up," Bergeron said to Emma Slater, Engvall's professional dance partner who believed she was going home.

Another first for the competition tonight was the live improvisational switch-up challenge, where there was no specific dance style known in advance, and the contestants were judged on their ability to adapt to completely new music on the spot.

Corbin Bleu won the first round, adding a much needed 4 points to his original low score of 23. Amber Riley won the second round, adding 4 points to her original score as well.

Tonight's week six episode marked the half-way point for the show's competition. All of the judges' scores from tonight, including the bonus points, will carry over into next week's results.

Tonight's Routines

Bill Engvall: The comedian danced a "redneck" version of the tango to Jimmy Buffett's "Cheeseburger in Paradise." The tango, a normally aggressive, passionate dance, was "well done" by Engvall, according to judge Len Goodman, who said Engvall's version was "sharp and tangy." Tonioli thought Engvall "lost the smoothness of the footwork of the tango," but still gave him a score of 8. "You did what you did best, which was entertain us," Inaba added. Engvall earned 23 points.

Elizabeth Berkley Lauren: The actress earned the first perfect score of the season with her sexy Cha-Cha-Cha to Joss Stone's "Put Your Hands on Me." Lauren's professional dancing partner, Val Chmerkovskiy, wanted to show off a different, more empowering side of her, and it paid off. "So sexy, it just killed me," said Tonioli. "It was so clean, it was so sharp. It was brilliant." Inaba agreed, comparing Lauren to a white tiger tonight on the dance floor. Goodman called the pair a "formidable partnership." Lauren scored a perfect 30.

Leah Remini: After her contemporary routine failed to impress the judges last week, Remini's quick step tonight was much more highly praised. Inaba called it the biggest turnaround she's ever seen. Goodman compared Remini's time on the dance floor to a game of Chutes and Ladders, saying, "Last week you shot down, this week way up." Tonioli even compared the actress to the legendary Ginger Rogers. "You can do it and you proved it," he said. "You were light and you moved well." All of the judges gave Remini's performance a 9, earning her a total of 27 points.

Brant Daugherty: The actor's sensual tango to "The Night Out" by Martin Solveig was received incredibly well by the judges, with Goodman comparing it to a glass of dry white wine. "[It was] sharp, crisp, tasty, no gimmicks," he said, giving Daugherty a perfect 10. Tonioli loved seeing Daugherty's progression and his ability to finally dance "like a leading man," saying he went from being a "prince charming" into becoming a "prince of darkness." The judges thought this was his best performance, with Inaba calling his technique incredible. Daugherty earned a 28.

Amber Riley : The actress earned perfect 10's from both Tonioli and Inaba, with the exception of earning an 8 from Goodman, who called Riley's samba "a tad repetitive." "I'm always the party pooper," he said. Inaba, on the other hand, thought Riley nailed every move and included all the perfect elements. "Every time I watch you, I can only think of the word 'fierce,'" Inaba explained of Riley's moves on the dance floor. Riley earned 28 points.

Jack Osbourne : The TV personality's Paso Doble earned a score of 9 from Goodman, who called the performance "top notch." However, Inaba felt this intense dance was a bit out of character for Osbourne, whom she called, "such a warm guy." Tonioli said Osbourne's "timing wasn't as good as usual," but "overall, it was a good effort." Osbourne, whose waltz earned his highest score of the season last week, only earned a total score of 25 tonight.

Nicole "Snooki" Polizzi: The star of "The Jersey Shore" danced an energetic Fox Trot to "Build Me Up Buttercup," adorned in a flowing yellow gown. "You graduated from charm school," said Tonioli, who gave Polizzi a score of 9. "You've never been so elegant." Inaba was equally impressed with her performance, saying the reality TV star has "really, truly improved the most," adding Polizzi has "turned into a ballerina on the dance floor." The judges awarded Polizzi 27 points.

Corbin Bleu: The actor danced a masculine Viennese Waltz to HBO's "Game of Thrones" theme song. "'Game of Thrones' is my all-time favorite show on TV right now," Bleu explained. However, attempting to perform like the show's barbarians may have worked against him. "Usually you have wonderful flowing lines … but playing the barbarian, it somehow lost its flow," Tonioli said of Bleu's interpretation of the waltz. Goodman admitted he "loved the theme," and "thought it was a wonderful interpretation," but ultimately, he "didn't really feel it was a Viennese Waltz." Bleu earned a total of 23 points.
