Sports presenter Ore Oduba has become the first Strictly Come Dancing contestant this series to earn a top score from any of the judges.
Ore and his dance partner Joanne Clifton were just shy of bagging a perfect 40 as judge Craig Revel Horwood awarded their jive a nine, while the rest of the panel gave it full marks.
The pair performed to Bruno Mars' Runaway Baby, with the studio audience erupting into cheers as they finished the routine, which bagged them 39 points and set them at the top of the leaderboard.
Craig told them: "The game has finally changed, darling, you are the one to beat in this competition and you know what, I hope Danny Mac was watching that because he's got a big load of competition."
Ore is hot on the heels of actor Danny - who got a score of 36 for his quickstep with Oti Mabuse - as the bookies' favourite to win the BBC One contest.
Head judge Len Goodman told Ore he was even better than last year's winner Jay McGuiness, who also wowed with his jive.
He said: "Showstopping, jaw-dropping, eye-popping jive. I thought last week was fantastic, you've had a week, listen, move over Jay - you've turned up."
As the scores came in with Darcey Bussell, Bruno Tonioli and Len all awarding 10s, presenter Claudia Winkleman said: "That was honestly better than my own wedding."
Meanwhile, at the opposite end of the scoreboard, politician Ed Balls has hit a new low with a total score of just 16.
Ed and his partner Katya Jones performed a clumsy paso doble to Holding Out For A Hero, stumbling over a number of missed steps.
Len told him: "I don't know about holding out for a hero, I was holding out for a paso."
Craig, who scored him just two points, complained: "The shaping was terrible, it was stompy, there wasn't a hint of any matador in there, darling. It was dreadful."
Darcey added: "It was a shame that you made that balls-up."
Ed, who was dressed as a knight for the performance, admitted: "A few things went wrong."
He has been bottom of the leaderboard each week so far, but Saturday's was his lowest score to date and the lowest in the competition so far.
Claudia addressed the departure of singer Will Young, who dropped out of the contest earlier this week citing "personal reasons", at the start of the programme.
She said: "Will, if you're watching, we love you and we wish you all the best."
The Strictly Come Dancing results show, which will see one couple kicked out of the competition, will air on BBC One on Sunday night at 7.15pm.
