Change Da World… My Final Message refers to an image macro series featuring bizarre characters captioned with the catchphrase "Change da world… my final message. Goodb ye." After the first iteration featuring a rat smoking a cigarette spread, a Twitter user made a video edit pairing the image with audio, leading to the creation of multiple other iterations.
Several months later, on October 12th, Tumblr  user dawatercup shared the image with the phrase "Change da world… my final message. Goodb ye" written in a digitally-altered, blue and white caption box. The post received more than 27,000 notes in less than one year (shown below, right).
On November 14th, 2018, the rat paired with the caption appeared on Imgur. On August 16th, 2019, Twitter user @comfygang posted a video of the image set to audio (post deleted). The clip uses a robotic voice reading the text over the song "White Noiz" from JungleJungle: 1989 – 1999 Sample Pack and the Windows 95 PC start-up sound. On January 19th, 2023, Twitter user @st1llstand posted a number of images and videosrelated to @comfygang's involvement with the meme (shown below).

The clip inspired others to remake the image with various other characters and set the image to comfygang's audio. Other examples include a video posted by Nitro.IF that gained over 6,400 views (shown below, left) and an example posted by Lemon'sMemes that showed Nelson the Bull Terrier that gained over 1,600 views (shown below, right).
