Weirdly enough, this quote is hilariously accurate if you consider COs to be IRL dementors.
From the wiki:
"Dementors are among the foulest creatures that walk this earth. They infest the darkest, filthiest places, they glory in decay and despair, they drain peace, hope, and happiness out of the air around them... Get too near a Dementor and every good feeling, every happy memory will be sucked out of you."
Replace "Dementors" with "Corrections officers" and I bet most people who've been to prison would say that's an accurate statement.
The only thing that sucks about this Michael Scott scene is that very few people remember the reference :( Prison Mike is fucking hilarious
