BK King VS Vader.....
I looked around everywhere for some video of it (including on the torrents) but it doesn't seem to exist.
There is a lot of discussion about it though, so I'm intrigued as well.
Apparently they just stand there staring each other down, and every time Darth Vader "breathes", the Burger King guy tries to breathe harder but I don't think they actually fight each other.
The interesting thing is that the 'Burger King' might actually be the more intimidating of the two.
