I have had this question in a window in a corner of my desktop for two days now - and STILL no clues!
The explanations obviously weren't very important to you so I wonder why you even bothered to ask?
The alternative explanation is that you were drasticly struck down by a stroke or heart attack between 12:40 when you asked the question and 12:43 when I asked you what the clues were. If this was the case then I apologise and wish you a full and speedy recovery.
