We Are Number One is a song performed by Robbie Rotten, the villain of the children's show LazyTown, from the 2014 episode Robbie's Dream Team. In late 2016 it exploded into a massive internet meme, with thousands of remixes and edits flooding YouTube after fans rallied around actor Stefán Karl Stefánsson during his cancer treatment. The chant became shorthand for playful villainy and ironic triumph online. Years later it still pops up in edits and soundboards whenever someone wants to crown themselves the number one bad guy.
