The 2006 dance floor destroyer has made a massive comeback on social media with the Sister Bettina Challenge, where people post crazy videos of themselves dancing to it.
In one video, a church choir group is singing their boring song, with one guy on the piano.
But then suddenly, Sister Bettina is played and they jump up and start dancing.
One goes as far as upsetting the couch, throwing the cushions in the air, while another lifts up a fellow singer and dances with him.
Another video shows students at a residence.
While the boys get into the showers, the girls are brushing their teeth.
