Slightly difficult to abide by that criteria through the written post. Mr B. could/should have recorded his sarcastic outpourings and foisted them upon teh forum for us all to enjoy in all it's deadpan glory.
Or he could've used blue text, but those of us that have been around him for a length of time are able to discern certain sarcastic cadences in his text. Perhaps if you asked him nicely, he'd be able to edit and highlight those passages deemed sarcastic thus nullifying any further confusion.
