Saw this exact question being asked in the peepshow subreddit, which I’m not subscribed to but came up in my recommended.
So thought I’d ask it here, my favourite minor character from South Park has to be halfy. He was literally in like 2 episodes and then we never saw him again :'(
Who’s yours?
Captain Hindsight. It gives me something to call those people who have to tell you what you should have done. “Thank you, Captain Hindsight. For nothing.”
