Might I suggest adding an opt out form? A way to submit your own number so it can never be called with the service?<p>All similar prank call services have such a form, which I discovered when some HN troll decided to plague me for weeks upon end.
Clever, and monetized. Wonder how the license holders of the content might feel about this, uh, approach? Time will tell, won't know until it gets tried, etc.
Couldn't I call them myself and hold the phone up to a speaker playing the YouTube video? At least then after I annoy them they can hear me laugh as they hang up and sigh at how juvenile I am, and wonder why they're still my friend.
