It was guilty pleasures night on Dancing with the Stars,
but one competitor had little to smile about after taking the second tumble of the season.
Three weeks ago, Maksim Chmerkovskiy and Kirstie Alley hit the ballroom floor.
This time perennial leaders Ralph Macchio and Karina Smirnoff suffered the mishap when Smirnoff tripped over Macchio and fell during their paso doble to "Everybody Dance" by C + C Music Factory.
But they quickly recovered and ended the evening – dedicated to songs you feel guilty about loving – with a respectable 24 points, making them more than safe going into Tuesday's eliminations.
"I'm proud of you, and you should be proud of yourself," said judge Len Goodman, and Bruno Tonioli gushed, "Once you got back on it, there was no stopping you."
, meanwhile, may have danced well enough to last at least another week, shimmying and shaking a samba with Louis Van Amstel to Ricky Martin's "Livin' La Vida Loca," garnering 25 to keep them out of last place (that is now occupied by Chris Jericho).
"Oh, my god, whoa," gushed Carrie Ann Inaba. "That was a guilty pleasure, my dear. … You were in your element."
But the night belonged to Romeo and pro partner Chelsie Hightower, whose waltz to the Titanic
theme "My Heart Will Go On" ended with them spontaneously kissing each other on the lips (Hightower says it wasn't part of the choreography.)
They also got the season's first perfect 10, from Inaba, on their way to 28 points for a night-leading tie with Chelsea Kane and an injury-hobbled Mark Ballas.
"Every once in awhile in a season, magic happens," says Inaba. "That was magic."
Hines Ward and Kym Johnson remained strong, collecting 27 points with a Viennese Waltz to "End of the Road" by Boyz II Men, though the judges got boos for suggesting Hines was still a little stilted and self-conscious.
Alley and Chmerkovskiy also had a good night with their Samba to "… Baby One More Time" by Britney Spears
. They got a 26 and high praise from Goodman.
"This season has been a season of misadventures," the judge said. "You haven't fulfilled the potential I saw in you week one – until now."
