Why do you give youtube the benefit of the doubt? You believe youtube to be a reliable source of information?
BBT is a popular TV show, I'm certain you are capable of finding it on a streaming service somewhere. If not there is the possibility of pirating it. You are capable of watching the show yourself to verify the claims coming from youtube. Or you could trust people who have seen enough episodes that tell you the youtbue video is false.
Or you can go on being a "I did my own research on youtube" type of person. I'm not your mom, do what you want to do.
