The song is called No by Vim and the meme most people remember is Eddsworld's Just A Bit Crazy (from 2008) which became it's own meme. However the original animation to use the song was a furry animation (from 2006) by Nobuyukinyuu (of Inspector Bonk fame). You should check them out.
@@X-SPONGED Experiencer really. I remember when the original meme came out. A flash animation of failing dogs on a scale. Then Eddsworld's coming out years later. It was actually relatively common for furry memes to go "mainstream" at least in Internet terms but have their history buried. Nyan Cat is an example.
I feel like I've found a cool exotic bird on my way home, thanks cyrakek for uploading this really was amazing that I found this video (youtube did not recommend this to me at all), found it by scrolling through dolan darkest and finding your month old comment about remnant (the game), remembered your name and clicked to check on your channel to find ur video
