This is how he describes the video and his skills: Me attempting to do 24 different accents from my own country and from other countries around the world. Hopefully I got most of them right but I may have made mistakes and I can do some better than others. However, I made this video for my friends because I promised them I would do an accent video. I mean no offence to anyone and please don't be upset if I have not included your specific accent or got it wrong.
In this video he is the speaker on a series of one-sided phone conversations; he swears (= uses bad language) quite a lot, so don´t pay attention to what he says but to how he says it.
