Here is a hilarious video clip from Pink Panther of Steve Martin attempting to learn how to pronounce English. Though very humorous, it is also a statement on how pronunciation is taught and learnt across the world. Though this clip takes the technique to humourous heights, the reality is that learning pronunciation through mimicry or copying has some serious flaws.
Have a look at this clip and then have a look at the video clip that I made and you will see huge differences between the two.
