Most mashups take the lines from a movie and place them over an unrelated, but oddly appropriate, scene. At best the dialogue mostly lines up with the movement of the mouthes on the screen but it's mostly about matching with the images.
Day Job Orchestra went the other way with this, matching nonsensical words that match the mouth movements but have zero relation with what is happening on screen. And it works. So what do you say we make apple juice and fax it to each other? (Link via Warming Glow)
