The two couples in jeopardy were Nicole "Snooki" Polizzi and Sasha Farber, along with lowest scoring couple, Bill Engvall and Emma Slater.
And the results? Polizzi and Sasha Farber were eliminated in yet another shocking dismissal, closely following Christina Milian's surprising farewell a couple of weeks ago, despite their earning high scores.
"I can't even talk right now," Polizzi said, barely fighting back tears right after her elimination was announced to a stunned ballroom. "I love everybody here, so it sucks."
Other notable moments of the night included:
Leah Remini and Tony Dovolani danced an intricate salsa that had a lot of lifts and turns, which judge Carrie Ann Inaba said was "like going to the hottest salsa club and you were the hottest salsa dancers."
Fellow judge Len Goodman argued that "the lifts weren't quite clean enough," though their routine still got 26 points out of 30.
Jack Osbourne and partner Cheryl Burke scored their first 10 of the season, with a jive that Inaba said was "perfectly suited for you." They ended up with a 27.
The first dance of the night to really leave the judges in awe came from Amber Riley and Derek Hough, who stunned with their 29-point Paso Doble that Inaba said "lit this ballroom up."
The lowest score of the night went to Engvall and Slater, whose 23-point Elvis-inspired quickstep was considered merely a "very good try" by judge Bruno Tonioli.
The comeback performance of the night went to Corbin Bleu and Karina Smirnoff, who were one point shy of a perfect score for their cha-cha, which Goodman commended for its "lovely crisp footwork," even if he was a bit turned off by Bleu's gyrating. Tonioli called the dance "immaculate, brilliant."
At the end of the night, all of the couples divided into two groups: Spooky Bon Bons and Foxing Awesome.
The first group's dance was Halloween-themed, with Polizzi as the standout. Also getting recognition was Engvall, who Inaba said was "the glue that held that performance." They scored 27 points. Elizabeth Berkley and Remini were also part of that team.
The second group, which included Bleu, Riley, Osbourne and Brant Daugherty, had a fox-themed dance that Tonioli called "so clever [and] so inventive … you killed it." Inaba called the perfect-scoring routine "super detailed." Everyone on their team was declared safe to go on to next week's competition.
