1. When he shared his wisdom via witty one-liners.
2. Or gently advised his younger co-workers against foolishness.
3. When he said what everyone else was thinking.
4. Or what no one was thinking about enough.
5. When he chose to be the only pacifist in the room.
6. And always managed to solve conflict in the most peaceful way possible.
7. Because he always had his priorities straight.
Like when Pete tried to get rid of Don by revealing his true identity and Bert was like "BITCH, PLEASE."
