Here's how you enjoy the clip: Play it in the background, and pretend you're listening to an actual mother talking to her infant in the next room. Only the last two sound normal.
I really have to wonder how that first girl got this job. Mommy Angela is clearly an old hand at this, the redhead is really stilted but still seems to have some sort of weird fetish training, but the first girl and the one with the lipstick both seem like sophomores who followed up a really weird ad in the college paper.
