Walker's first video to reach a million views compared the cost of doing five bags of cocaine in Australia versus flying to Mexico for the weekend; a viewer later claimed (via a screenshot) to have actually done it.
Walker drew constantly as a kid until an art teacher harshly dismissed his work, causing him to stop drawing for a decade until he started copying a stoner housemate's drawings for fun.
While working in sculptor Mark Shatner's studio, Walker was told that art is about building a 'brand in someone else's head' through consistency, not pure creativity. Shatner told him to pick one image and medium; Walker chose ibises he saw in Hyde Park and drew them daily for a year, eventually evolving the drawings into comic strips with jokes.
Walker made a satirical 'bro science' documentary claiming vegans get better ecstasy highs, intending it as a shitpost; it drew praise from some vegans but provoked death threats from angry 'bro science' meatheads.
