Wikipedia Brown

Wikipedia Brown turns up as a background gag more than a fixture of the plot — a walking pun on the boy-detective archetype crossed with crowd-sourced trivia. He's confident to the point of insufferable, ready with an answer for everything, even when nobody asked and even when he's wrong.

The joke is entirely in the name, and John DiMaggio sells it by playing the character with total, unearned authority, never winking at how silly the premise is. It's a small, disposable bit, but it lands because the delivery treats a Wikipedia pun like serious detective work.
