Boo Teaches Human Anatomy 101

I'm very proud Casey devoted three years of his life to grad school to learn his profession.  Yet sometimes, I wonder if it was a little over kill.  Boo pulled out one of Cak's anatomy book and proceeded to teach Bug.  Maybe Casey only needed a year, and Boo to be a physical therapist. 

See what I I'm saying?  Grad school is way over-rated!
