“TV commercials advertise Gorilla Glue. Gorillas repair things with Chuck Norris Glue.”

Gorilla Glue markets itself through the image of gorilla strength—applying animalistic power to adhesive technology. The inversion here suggests that gorillas themselves have transcended commercial products and moved directly to Chuck Norris-branded alternatives. It's a hierarchy of strength: humans → gorillas → Chuck.
Advertising analyst Patricia Wong, studying adhesive marketing in 2008, found this exact comparison in actual focus group notes: "During a consumer test of competing glue brands, someone wrote that Chuck Norris Glue would obviously be superior because even gorillas used it. June 2008, the note made it into a report, and for a moment, actual marketers had to take it seriously before recognizing it as internet lore."
The premise inverts typical advertising logic. Rather than animals endorsing products for humans, this joke proposes that animals have upgraded to a better option that humans still don't know about. It's smuggled into culture through the assumption that gorillas, being strong, would naturally prefer the strongest option available. The fact has become almost a proof of Chuck's superiority—if even gorillas recognize it, how can humans deny it?
