"We Are Number One" is an upbeat song from the children's television show LazyTown, performed by the antagonist Robbie Rotten (played by the late Stefan Karl Stefánsson) as he attempts to teach three incompetent clones how to be villains. The song became an internet phenomenon in late 2016 through a surge of highly edited remixes and parodies on YouTube, often used to raise money for Stefánsson's cancer treatment. The meme is celebrated for its wholesome community roots and its versatile format, which typically features Robbie Rotten's eccentric expressions and the slapstick failures of his team. It stands as a lasting legacy to Stefánsson’s impact on digital culture and the power of collective internet humor.
