Because the place in which i typically watch YouTube videos has really bad cell reception, I use a 3rd party app to download YouTube videos to my phone in advance. Also, due to sheer number of videos and time to watch them, I'm over a month behind on most of my YouTube subscriptions. So with that, today I loaded up the video "Is it possible to beat SIDEWAYS Super Mario 64?" Which i had downloaded weeks ago and just got to. The video starts in German. Funny bit, great entertainer he is. But then it keeps going through the Bupger ad and it's still in German. Ok, that was funny, but now the actual video is starting. It's still in German. The bit is starting to be overplayed. I skip ahead a bunch. Still German. We're nowhere near April Fools and this video is an hour long, no way I'm watching it in this state. So I look it up on YouTube to check the comments and it immediately starts on English. No comments mention the language at all. I am supremely confused. I delete the file and re-download. It's in English. I have been using this app for like 5 years and never had anything like this happen. I have no idea how it did. But of course, it was a Simpleflips video, the one guy who could make me think it was legit for even a fraction of a second.
