sorry this gif is not available in your browser
One of the great things about the animated GIF format, despite its many other deficiencies, is that it works everywhere. Even stodgy old browsers can display it. Naturally, this fact means that whenever an animated GIF is uploaded to twitter, they convert it to a format that fewer browsers can display.
The “Download File” text floating towards the bottom left links to an MP4 file of what was once the GIF. Just one more way developers are working to make the web a better place. Thanks guys!
