Dancing Through the Years: Unforgettable Moments on 'DWTS'

'Dancing with the Stars' is celebrating a big milestone with episode 500. But let's not forget some of the show's most awkward and memorable moments. Live TV can be unpredictable, and 'DWTS' has had its share of surprises. Back in season 2, rapper Master P set an unwanted record. He scored the lowest in the show's history with an 8/30 for his Paso Doble. Replacing his injured son, Romeo, Master P's stiff moves didn't impress the judges. Season 10 saw reality star Kate Gosselin and pro Tony Dovolani have a heated argument during rehearsals. Their different learning styles clashed, leading to a tense moment caught on camera. Olympian Ryan Lochte's first dance on season 23 was interrupted by protesters. They rushed the stage as Lochte received critiques, causing a brief commercial break. Lochte was trying to recover from negative publicity from his time in Rio. In season 5, singer Marie Osmond collapsed during her Samba performance. Feeling lightheaded due to wildfires, she got medical attention and returned to the show. Pro dancer Maks Chmerkovskiy had a fiery exchange with judge Len Goodman in season 13. After Len criticized Maks' dance with Hope Solo, Maks suggested Len should retire. The other judges stepped in to correct Maks. Front-runner Sabrina Bryan was unexpectedly eliminated in season 15. Despite high scores and fan love, viewers might have assumed she was safe and didn't vote. Sabrina and her partner gave their best, true to themselves.
