Anyway, here are two sample videos to give you a feel for DTTR. However, if you feel this isn't relevant enough for a language thread, I understand.

There's a German girl named Trixie who has a YouTube channel named "Don't Trust The Rabbit" and she has a LOT of videos about the German and English languages. In and of themselves they won't make someone fluent in German, but I thought they might be of interest to people trying to learn German, or for that matter, Germans trying to learn English.
She does English lessons too
I think this video is funny, https://www.youtube.com/watch?v=yR0lWICH3rY
One thing that's remarkable about Trixie is that she's become fluent in English without visiting the UK or USA. It helps that she's done a lot of work, but I think a more important factor is that she has a job in Hamburg as a German teacher working for an international company where everyone speaks English. Speaking English with other native or fluent speakers is bound to improve your own language abilities.
I'm going to post the link to two of Trixie's other videos. The first which shows how her German accent has changed. From these clips, I don't think Trixie's English a few years ago is bad, but it's clear that her accent is stronger and her pronunciation could use improving---which it has. The second clip shows that her fluency in English has come at a price since she's having more and more trouble remembering words in German. Keep in mind that she is still in Germany!
