The 'Carl Wheezer Has Judy Neutron in a Jar' meme is a dark humor crossover that blends Carl Wheezer's established canonical crush on Jimmy’s mother, Judy Neutron, with the infamous internet jar legends. The template typically features an edited image of Carl gazing intensely at a glass jar containing a Judy Neutron figurine, symbolizing a level of obsession that ranges from hilariously awkward to deeply cursed. Since its emergence on platforms like Twitter and Reddit, it has been used to represent niche hobbies, intense fandoms, or the act of finally 'catching' something long-desired. It remains a staple of Jimmy Neutron shitposting culture due to its unsettling yet nostalgic aesthetic.
