Yeah, I've loved movies where some of the best jokes happen in the background.
And I imagine a scene where Dark Helmet is walking down a corridor that becomes shorter and shorter. As he hits his head, his face contorts in pain, as if he's yelling out.
"Oh god, that looks painful", one of his aides remarks, "But how come we don't hear anything?"
"Speed of Light vs Speed of Sound", another remarks." You'll hear it in just about.... *and they all cover their ears as the loudest string of curses finally catches up to them*.
"Should we help him??, "the first one remarks again
"No, he'll be fine. This corridor was never designed for helmets like his."
Another joke when he introduces his son.
"Well, where is he? I don't see anyone. "
"Right here, you grunts!" a small voice comes from close to the floor. "You'll listen to me if you know what's good for you."
"Aww, how cute. He's... tiny. What do they call you, sir?"
"Don't you dare call me tiny! My Schwarts is bigger than yours! You'll call me Big Daddy."
"Say sir, *motioning towarsd Dark Helmet* , "I don't think we want to know about the mother."
