MILTON, MA—Longtime Jeopardy! fan Brian Kalorcz surprised himself Tuesday when a category on the popular game show revealed that his brain housed an unsuspected wealth of weasel-related knowledge.

"What is the Mustelidae family? What are mink, polecats, and ferrets?" Kalorcz recited from his couch, his expression changing from mild bemusement to genuine alarm as he effortlessly responded to weasel-related statements made by host Alex Trebek's on-screen image. "Who is Pauly Shore? Christ, where the hell is this all coming from?"

Kalorcz admitted that he was unsure whether to be relieved or upset that he did not know the Daily Double clue concerning the 1970 Mothers of Invention album Weasels Ripped My Flesh.
