30 couples in the Indian capital Delhi are waiting to see if they've boogied their way into the Guinness Book of Records after dancing for 55 hours.
The monster shin-dig took place in a sports stadium in the heart of the city, with official competitors on stage and others free to join in.
Ten of the city's top DJs kept the music pumping while the couples shook their increasingly tired stuff.
They're now waiting for officials to verify they're the new record holders.
Strict rules
The previous record was set in the US, when people danced non-stop for 52 hours and three minutes.
Guinness rules about dance-a-thons are very strict.
At least 15 couples must be dancing at all times, and 75% of the first dancers on the floor must be dancing when the dancing ends.
Towards the end of the attempt, most of the groovers were tired and barely moving, but none of them got off the floor.
Vidya Tiwari, 18, said: "I was here to break the record and did not stop till I had achieved it."
