CuteWinFail is a channel made by Tobuscus. CuteWinFail (shortened to CWF) was a weekly web-series where Toby Turner reviews three videos, and puts them in the category "Cute", "Win", or "Fail". Then, users vote for which video is the most epic in the comments. The videos that don't get the most votes get crushed into smithereens by giant words. A lot of the videos involve animals, and at the end of each video, Toby shows a clip of "One more dose of epicocity" (formerly "stupid freaking babies doing baby stuff" and "puppies humping things" before that).
All episodes can be seen on the official CuteWinFail YouTube channel.
