You Will Never Be Able To Watch "Friends" The Same Way After Seeing This

Do you ever notice something, and from then on can NEVER unsee it? I think that's what just happened to me after watching this video. A "Friends" fan noticed this pattern of delivery Jennifer Aniston had while delivering her lines-- she seems to clear her throat nearly every time she delivers a line.

Check it out for yourself below... but watch at your own risk because now that I've seen it, I don't think I can ever NOT see it.

Did she do this for the whole series and no one ever noticed? How has this not been pointed out until now?
