I've totally had this happen to me too! And I sort of remember seeing Arnold's dick just the way you said. That's pretty weird.
I've noticed it most noticeably on TV shows like Star Trek.
I clearly remember seeing an episode of Star Trek TNG from season 7 "Parallels" twice an there were a few differences. Like one scene was cut short and a whole new scene was added. Of course on TV they do all kinds of cutting for commercial purposes.
wow, that was disappointing. Frankly, I expected his dick to be a lot larger.
Maybe it simply because his arms and legs are so huge and muscular it dwarfs the image of his dick.
