Yeah, and that's why I'm freaking out. Mate, I can't get rid of the accent. I even tried doing an American accent. Look.

[Derek attempts to do an American accent but it comes out a horrible attempt at a standard America accent with hints of southern flair.]

My name is Derek Matthews and I can speak proper American English.

[Derek reverts back to his now current English accent.]

See, I can't do it! Bloody hell I sound like a complete tosser!
