In the HBO series Game of Thrones, there is a character who is the heir of a deposed king: Viserys Targaryen (Daenerys Targaryen's brother), who longs for a wonderful golden crown. Well, he's a jerk, so he gets his golden crown in an unexpectedly nasty manner.
And so I thought it might be fun to see a joke ad for a gold investment business like Goldline, where the spokesman raves about how awesome gold is, and so the Dothraki show up and say if they love gold so much, here's a molten golden crown for them, and they pour it on their head at the end of the ad. Then there could be some disclaimer that says most investors do not have Dothraki show up and pour molten gold on them, so it really is a good investment, for most people, most of the time. And even if you get the molten golden crown, at least your family will still have the gold, which will only increase in value.
BTW: This, for those who are unfamiliar, is how Viserys Targaryen gets his golden crown:

Now wouldn't that make a great ad for Goldline? Maybe they could even say that if you buy gold from them, they'll heat it up and pour it on anyone you want, and then you can just keep the gold afterwards.
