When Alesha Dixon performed his show-stopping routine on series five, we were convinced she was about to become the next Beyoncé. Instead, she later became the next Arlene Phillips, replacing the veteran on the panel.
Sophie Ellis Bextor's Charleston
The Charleston was a fairly new dance to 'Strictly' when S.E.B took it on in 2013. And despite it only being week two of the competition, she and partner Brendan Cole bagged a whopping 36 points for the routine.
Danny Mac's Samba
Danny and Oti's 2016 routine still makes us come over a bit funny. Let's put it this way - if it was any hotter, it would have been on literal fire.
Abbey Clancy's Waltz
2013 champ Abbey wowed the judges with this beautiful waltz in week one of the competition, and brought it back for the final, where they scored a perfect 40 and lifted the glitterball trophy.
Jill Halfpenny's Jive
If you can remember as far back as series two in 2004 (!), you'll no doubt remember this knockout performance from Jill and partner Darren Bennett.
Lisa Riley's Samba
We don't think anyone has ever had as much fun as Lisa and Robin Windsor did performing their Samba on the show in 2012.
Caroline Flack's Charleston
Cazza's Turkish interpretation of the Charleston cemented her as the favourite to win in 2014. She also performed the dance again in the final, which eventually saw her crowned winner.
Kara Tointon's Argentine Tango
Given the sexual tension in this performance, it's no wonder Kara and Artem Chigvintsev announced they were an item shortly afterwards.
Louis Smith's Showdance
Not only did Louis Smith capture a lot of attention with his toplessness, but his dancing was pretty good in this too.
Matt Di Angelo's Salsa
Matt went from Dean Wicks to snake hips with his performance of the Salsa in series five in 2007.
