Seems there is a lack of common fan base
For those of you who don't get it (not sure I do yet) there is clearly an inside joke going on. Both Egoraptor and HotDiggedyDemon did flashes like this (with great voice acting). Released on the same day too.
Something is going on behind the scenes. I found them both funny - not 10 funny - but funny. The 10 is because of the added unsaid collaboration. Egoraptor mentioned a third guy? Who is the third?
