When you get your nice big refund from the tax man I can point you towards an excellent investment opportunity. Indeed, why wait? Rather than risk losing out, you can invest your existing capital now. All you have to do is to lend your bank account to this nice Nigerian prince that I know (because he's experiencing certain difficulties with the international banking system) and he guarantees to double your balance after just one month. (He has to put a limit on it though. You can't benefit by more than US$10,000,000). What could be easier?
