Alex Apollonov is an Australian YouTube personality and comedian, better known for his online persona I Did a Thing, and his YouTube channel of the same name. He is also the co-star of Boy Boy which he created with fellow comedian Aleksa Vulovic who also stars in his videos. Much of his content involves himself creating home-made devices to comedic effect, including recreating the Utah monolith in Australia, simulating the Aurora Borealis in his kitchen to parody The Simpsons, making steel-toed crocs, alongside a number of projectile weapons firing tampons and napalm. Often his videos will contain commentary on politics and global events, including climate change in Australia, the lethality of rubber bullets, Australia's colonial legacy and recently the COVID-19 pandemic.
