"Dancing with the Stars" invited its contestants to recall their Most Memorable Year on Monday -- but the night ended up being one that Nancy McKeon would rather forget.
The former "The Facts of Life" star and her partner Val Chmerkovskiy were sent home after scoring 22-out-of-30 for an emotional rumba inspired by the year 2006, the year McKeon and her husband completed their family by welcoming their second daughter.
The other couple in jeopardy, but eventually deemed safe, was R&B singer Tinashe and her partner Brandon Armstrong, despite the fact that they've consistently been among the high scorers so far this season.
Monday night also saw the first 10s -- and the first perfect score -- of the season. Argentinian actor Juan Pablo Di Pace and his partner Cheryl Burke blew the judges away with a samba inspired by the year 1999, when Di Pace left Argentina to make it as an actor.
Judge Bruno Tonioli called it the best samba he'd seen in 27 seasons, while Carrie Ann Inaba called it "off the charts." Judge Len Goodman gave them a standing ovation -- and a 10, and so did Tonioli and Inaba, for the season's first 30-out-of-30 score.

Among them was gymnast Mary Lou Retton's recollection of how, in 1984, she won the gold medal at the Olympics, despite having secretly undergone knee surgery just six weeks before the event.
Country radio personality Bobby Bones recalled the year 1998, when he graduated from high school, because he was the first in his family ever to do so. His mother had him at age 15, struggled with addiction and then died in her 40s as a result of drugs and alcohol.
"Harry Potter" star Evanna Lynch recalled that before she was cast as Luna Lovegood in the Potter films, she had an eating disorder and was frequently hospitalized. She reached out to her favorite author -- J.K. Rowling -- and they became pen pals, which she said made her want to continue living. Strangely, her relationship with Rowling had nothing to do with her getting the part of Luna.
Former NFL star DeMarcus Ware cried as he recalled how he and his wife lost three pregnancies before adopting a baby girl, and then getting pregnant and having a son two years later. DeMarcus recalled that during his most memorable year, 2016 -- the year he won the Super Bowl -- what meant the most to him was that his wife and two kids were there in the stands cheering him on.
