We had to check the date on this – but no, it's not a premature April Fool's story…

A US software company is selling a special downloable font character (currently only available for Windows PCs and Blackberrys) called a 'SarcMark' (it looks like an upside down @) that you can type after a phrase, sentence or comment to show you are being sarcastic – so you don't inadvertently offend readers. You can find more details here

There is even a YouTube video to watch although we can't help feel that some of SarcMan's comments are rude, rather than sarcastic. We'd like to propose an alternative: a 'MoronMark' (or MoMark) you can type at the start of sentences to warn people that if they lack a sense of humour they might not understand what follows.
