I should point out that i'm English, Roy Castle and Roy Walker were rubbish 80's T.V presenters over here, a "Twix" is a chocolate bar and we spell ass as "arse"!
Haha apparently the English spell 'ass' incorrectly and over-post all their thoughts!! (Note: I actually already knew both these things - - - ACTING!!!).
As a resident of the UK (not for long, if Alex Salmond gets his way), I enjoyed these references. I myself use the proper English spellings of words like "favourite" and "colour" in my strips, but I haven't done anything overtly British.
Still I really enjoy these strips in and of themselves, so good work.
