So while this could be considered slightly on topic I recently saw this video and then I was sort of reading some of the Brewster scene where Andrew is doing an Australian accent in text to the best of his ability and I thought I'd plop this down for anyone who hadn't seen it yet(it's viral so that number I imagine is fairly small.)
There's some NSFW language in the video, and even the individual will warn you of the same. Somehow when speaking random things he generally reverts to mob/gangster movie style angry phone calls. Still, some good stuff, if only mostly stereotypical.
