Memorable NPCs of No Significant Power

A lot of campaigns have NPCs that are memorable while being extremely powerful; be it high-level villains, upper-class types with enormous resources, patrons who could grant (or take away) boons to the PCs, or significant allies that had power or resources that could help the PCs in their causes. But what I want to know about in this thread were those NPCs who had none of that, that were very low-level (or 0-level) characters and were not otherwise remarkable in terms of what they could 'give' the PCs but somehow stood out as very memorable parts of a game.



What was it about them that made them stand out? Was it a question of personality, or something else?
