Well as those in the know will remember there was once an Ask Ducky thread, and in fact it was recently suggested that he bring it back. I happen to be in favour of this suggestion, but as yet the legend has declined, so stepping into breach KKW's secondary legend will start an "Ask Hazzle" thread.
Ask me any question you like. Whatever kernel of universal knowledge you seek, the Haz is at your disposal with his words of wisdom. The answer to life, the universe and everything is at your beck and call. And no, it's not 42! My giant brain and even bigger ego are always at the disposal of the Wavefront and I will endeavour to deliver the answers promptly, and I will answer all questions asked of The Oracle.
So ask away.
