A viral advert is where some company commissions a video, made to look like a genuine amateur recording, in order to somehow advertise themselves. People often debate over whether these videos are fake or real.
I wasn't sure if the video you linked was authentic or contrived.
Oh...well I don't know then its hard to tell...any video on youtube can be a viral advert then. It doesn't look like they were trying to advertise anything in that video though.
You can never be sure I guess....but as long as you're a family man it shouldn't be a problem for you LOL!

I get real cravings for mushroom (esp. shittake) and fish sometimes, I wonder if its because I am low on D...most likely

Fortunately I can pig out on shrooms, haven't done that in a while I should go and get some.
I think taking the fish oils is really the easiest way though, they never gave me any problems and seem to be digested well.
Last time I had to have cooked cod (I had no choice was the only food around and I really wanted some meat protein), so I dumped like four tablespoons of cod liver oil on top of the cod steak, OMG that went really well together, I could have topped it with shittakes but I had none.
Fish and shrooms are definitely one of my favorites.
And now that days are so damn short I crave them more.
