So the sun will become a gigantic diamond when it burns out in a few billion years' time. Sadly, no aging billionaires will be around to buy the love of any dumb blondes with it. What a waste. (Erm, excuse the un-PC stereotype. Make that: no dumb blondes will be around to buy the love of any aging billionaires with it. Is that better? Okay, how about rich brunettes? Highly-intelligent redheads? Destitute billionaires? I'm just making it worse, aren't I?).

Oh well, I hear diamonds are much overrated as an investment anyway.
