I can't believe nobody noticed this in over three years, but at 1:14:26 on the DVD and 1:16:16 on the rifftrax, Disembaudio mimics the raspberry noise that Toad makes after he kicks Storm down the elevator shaft (which is technically not a raspberry, but more like a horse noise - but I don't know the term for that). I would suggest adding this to the text file, since it's pretty annoying to have to reauthor due to a synch line that slipped through the cracks.
Of couse, it blends in so much that nobody ever noticed it, so it doesn't work very well as a synch line. It could just as well be deleted since there's a real synch line two minutes later. Either way... that happened.
