I found it on a wonderful, (but difficult to search) Russian site: https://ok.ru
If ever you want to find where a picture came from, this will sometimes work:
Download the meme and if you can, remove the caption, (In Photoshop ?) not always necessary.
then go to Google - click on 'images' - find the little camera in the search bar - click on this:
upload the image - You should find the Sly Red Fox in the results.
I hope this makes sense :~)
I often try this when I find a post that has been partially obscured by annoying captions and I want to use the image as a template.
