Oh, no. I'd currently be DMing a campaign with "I...am Sancho", Dobra the Taxman, Guy Krueger the sorcerer who prefers punching people, and an awakened panda.
I use those characters because I get to be the goofball with them, not so the players can torture me. I have now learned that DMing my NPCs would be my own personal hell, so thanks, I guess.
