"Mr. Brown: Now this is a simple acronym: H.E.R.O. At Diversity, we believe it's very easy to be a hero. All you need are: Honesty, Empathy, Respect, and Open-mindedness.
Dwight Schrute: Excuse me, I'm sorry, but that's not all it takes to be a hero.
Mr. Brown: Okay well, what is a hero to you?
Dwight Schrute: A hero kills people, people that wish him harm. A hero is part human and part supernatural. A hero is born out of a childhood trauma, or out of a disaster, and must be avenged.
Mr. Brown: Uh, okay, you're thinking of a superhero.
Dwight Schrute: We all have a hero in our heart."
