Who You Gonna Call?

There were some crazy costumes in the ballroom when a Performance Show fell on Halloween in Season 13. J.R. Martinez and Karina Smirnoff proved they ain't afraid of no Tango as they danced to the theme from Ghostbusters. Karina wasn't an invisible specter, though most of her outfit seems to have disappeared as she and J.R. scared up some solid scores in a frightfully fun dance.
