Robomatic, I think it was: "Gentlemen, you can't fight in here, this is the War Room!"

I've always liked two lines from "The Blob" (which introduced a new actor, Steven McQueen): "It must have devoured the old man completely." And, after they blasted the blob with top-of-the-line superpowerful weaponry: "It didn't work."

Aloha,
