[Munch's Master]

Accents I can do: Pakistani/Indian, Welsh (sometimes), Scottish (soemtimes), Irish (Republic and Northern), Texas American (badly), Brummy (sometimes), Australian, Yorkshire/Lancashire.
Stereotype vocies like pirate and mobster voices can be done by pretty much everyone, in my experience.
I say sometimes because there's times when I try to do those accents and fail miserably.

I can't really impersonate many characters, I can do Agent Smith, Bubbles out of Little Britain, Brian Potter and Max out of Phoenix Nights, Munch and Mudokons from Oddworld, but that's it.
