It doesn't have to be an evil prank to celebrate April first. But it helps to celebrate with others, especially if it can be shown on YouTube.
On Tuesday 1st April 2014, eight climbers were treated to a big surprise, a world-first flash mob 134 meters above the Sydney Harbour in a salute to April's Fool's Day.
The unsuspecting climbers began ascending the iconic bridge for what they believed to be a traditional BridgeClimb experience, climbing one of Australia's bridges. When they reached the top they were surrounded from all angles by a 30 person strong flash mob.
The troupe launched into a synchronised routine to songs by Pharrell Williams, Katy Perry and Justice Crew at multiple locations on the Bridge summit. The climbers also decided to join in the dancing.
Once the dance steps concluded, the ensemble dispersed and the eight honouree flash mobbers resumed the journey of 1,332 steps along the impressive steel structure. Back on The Bridge Climb, they enjoyed unobstructed vistas spanning as far east as Bondi and as far west as The Blue Mountains.
