A group of dancing Stormtroopers wowed Simon Cowell and became the fifth and final golden buzzer act on Britain's Got Talent.
Boogie Storm performed to a medley of pop classics like Beyonce's Single Ladies and Psy's Gangnam Style.
Their routine incorporated signature moves from music videos including Psy's horse-riding move, and the nae nae.
Cowell led the applause, standing up with fellow judges David Walliams, Amanda Holden, and Alesha Dixon, and then hit the golden buzzer, sending the group straight through to the live shows.
He said: "I don't know who you are, but I literally said 'If we could find Stormtroopers who could dance' - seriously, I said that - 'this show is going to go into a different league'.
"My dream has come true. Thank you."
Elsewhere on the show, Tumar KR from Kyrgyzstan got four yeses with their routine incorporating robotic moves.
As one member demonstrated how far he could twist his body, the audience shrieked, Cowell put his hand over his mouth in horror, Walliams grimaced, and Ant and Dec cried out.
Anne Klinge also swept the judges off their feet with her unusual foot puppetry performance of a love story.
"It was a little piece of magic," Walliams said, and she left the stage with four yeses.
Singers The Garnett Family - choir teacher Helen, 46, and her daughters Rachel, 20, and 17-year-old twins Anna and Abigail - showcased tight harmonies as they sang Jess Glynne's Take Me Home.
