My favorite weird little guy was a halfling rogue, but he had an academic background. So he played like this overly optimistic nerd who just wanted to make the world a better place. I was playing him in a way that his optimism would fail when facing reality, but I kept rolling 20s. "Couldnt we all just get along?" Solved two conflicts. The best one was, "perhapse you have forgotten the power of love!" Convinced two dragons who hated each other to date. I miss that little guy. I still use his voice sometimes.
