During the show's fifth week of competition, Martinez and professional partner Karina Smirnoff visited The Conga Room in Los Angeles to get a feel for samba dancing, and that led the duo to pull off the sharpest, most entertaining performance of the evening.

It was also the first week since week one that Martinez and Smirnoff topped another favored team, Ricki Lake and partner Derek Hough.
