as you were looking for a video on YT, you see a video that's Very interesting, you click on it and it says "This video is unavailable" and you refresh it. And it doesn't show the video. And you refresh again, still don't but the name of the video is called "Error 404" and no comments. And it a error message pops up and it says "Please do not try to refresh the page Close YouTube and try again later." And you keep refreshing and it says "Dear viewer this is the last request to close YouTube, further refreshing of the page will lead to irreversible consequences!!! And the rest is your choice.
