1.
The supreme leader of all the Grammar Nazis. He is the ultimate Grammar Nazi and puts all others to shame with his amazing grammatical-ness.

Oftentimes synonymous to 'English teacher', unless your teacher happens to be of the lazy I'm-only-here-for-the-cash variety who spends all of class on Facebook.
Jake might be a Grammar Nazi, but Josh really is the Grammar Hitler.
