Those all had more to do with BK's ad agency at the time, Crispin Porter + Bogusky (http://en.wikipedia.org/wiki/Crispin_Porter_%2B_Bogusky). CP+B is famous for creating highly viral, somewhat weird, vaguely unsettling campaigns.
My friend worked at CP+B for a while (he's now creative director at EVB). I don't think he worked directly on the BK stuff, but I think he did have a hand in some of it. What he did actually work on was most of the Dominos commercials, (the LARPing and exploding car bit), some Best Buy stuff, some viral things. We used to get private youtube links of a lot of their commercials before they aired.
