Why I Want to Be Queen

Say You, the Queen (Queen Elizabeth, not some other Queen), are poking around a back room of one of Your many palaces. (OK, You aren't poking. You have carefully-screened People who are paid to poke.) There is an old painting, covered with centuries-worth of gunk, in this room. It's worth x-amount of pounds because it's old. This is nice for You, if a tad ho-hum...You own so many other pieces of Art, after all. But, wait! It turns out, as reported in the BBC News World Edition, that upon further investigation of this grimy old painting, You own an original Caravaggio! Your first! Worth tens of millions of pounds! And You don't have to dust it!!! (Truthfully, one cannot imagine Her Majesty breaking into a little victory dance and whooping, but, boy! Wouldn't the not-dusting part be just the time to do so?)
