Gotten this one (the "FANTASTISKT!") a few times now. First time I just panic-closed the page because loudness. It auto-plays a fanfare when the ad is fully loaded.

I can't prove it autoplays without mouseover just from that link, but you have my word that it does. It was at the bottom of a page that I hadn't even started reading it when the fanfare blazed.
