The bozone layer: The bozone layer prevents good ideas from penetrating—these days, also known as college.  

The bozone layer comes from the word bozo and the word ozone. 

A bozo was originally a muscular, low-intelligence male.  Bozo likely came from the Spanish word bozal (a muzzle) and once referred to those who didn’t speak Spanish well. 

Ozone comes from the Greek word όζο (ozo).
