Agreed. I watched it again, but this time I closed my eyes during the "bah" scenes (especially when the guy was switching back and forth). Much harder to make out the "fah" sounds when you can't see it since he wasn't saying that to begin with.
Now that I think of it, did anyone notice the narrator's voice had a bit of flutter to it? The program seems fairly new, but the narrator made it seem like a documentary from the early 80s.
