You're over brown townyzing it too much. The only reason why I did the "keep on smiling thing" is because I say that at the end of all of my videos, so I just thought of that way to throw it in there. The whole "Indestructible" thing will be explained when I make the video of the back story to this.
Well I might be over brown townyzing a little, but I also noticed one other thing-
I think the line explaining the bomb in the bell wasn't executed very well. I didn't hear what the line was exactly the first time I watched, but I didn't feel like rewinding. But the 2nd time around I heard the entire line and it sounded kind of silly.
They put a bomb in the bell, nobody knows why, there's just kind of a bomb there. And nobody thought to remove it. I know it might seem necessary, but explaining that "if you pull the string it will explode," also sounds a little odd. I don't know how I could have made it better- so I don't blame you, but it doesn't sound right. That's probably one of the things that made reactor worker think the video was funny, that just seems like a very random thing to say - "They put a bomb in the bell, dunno why, but I think I'll kill myself with it."
But remember I'm trying to give constructive criticism. These are all little things that add up, but overall I still think the video is alright.
