I found a gif on reddit that I really want to know more about.

Apparently, the gif is originally from Tumblr, but I can't find the original post.

Here's the media Tumblr link:

Does anyone recognize this gif? Maybe it's a commercial of some sort?

I think this was a commercial in the UK, for some sort of breakfast cereal / cereal bar thing.

I remember the name Chocolate Fool associated with this GIF, though I don't know if that's the product name or a reference to the man depicted.

The advert was the UK advert for Rice Crispy squares chocolate

Took a while, but I found the original commercial:
