This probably entertaining for only 30 seconds, but I'm always amazed by the people who come up with absurd ideas like this: this site plays any Youtube video of your choosing on the monitor of a virtual arcade cabinet, then after a few seconds takes over whatever you're watching with 'Mortal Kombaaat!"

So, if you're going to watch a Youtube video that you know you'll be bored with after a few seconds, you can now plan ahead to interrupt it with the Mortal Kombat techno theme and clips from the fighting game's movie adaptation. Surely, something this useful needs an iPhone/iPad app.
