LOL! You're absolutely right about the mouth, Colin.  In the newer video, they deliberately cut away to avoid it being so obvious.

Big mouth aside, she is still exceptionally talented and beautiful; we should all be so fortunate.  

Couple of interesting facts about Krystal Meyers...

One:
Her dad is Rick Meyers, the author of E-Sword Bible Software http://www.e-sword.net/  I've used it to prepare a lot of sermons, it is pretty good.

Two:
The average human mouth can open to a maximum of 12% the size of their head.  Her's has got to be twice that.  Seriously, check out the both the videos on here.  I was watching it with my daughter on my lap and she shrieked out in fear, "Daddy, she's going to swallow us!"
