The reason Sam Hyde never actually says the N word is because he still have, in the back of his head, a dream to be the host of some sort of pop internet/tv show. But he knows he can't ever have that if theres a video of him actually saying the N-word. The N-word however, does have written appearances in his little internet video series thing. But, if that ever comes into question he will reason his way out by saying "Oh I'm not editing the videos, I usually let some guys do that for me, if I had seen it before I would have talked to them about how thats wrong!!" and he would also act upset.
