I don't see any mention of the YouTube adblock trick, so from the vid:
Copy YouTube URL. Paste it in Bing and search. Scroll passed Bing's sponsored bullshit and click on the thumbnail for the video you searched. It will then play, still in Bing, with no ads.
So if you're on a work or government or w/e computer that doesn't allow installing adblock extensions, there ya go. No downloads or anything, just YouTube and Bing.
...this is the first time I've ever had any interest in using Bing, lol.
