For 16 years, SNICKERS has blamed strange human behavior on hunger. Now BBDO Chicago has decided artificial intelligence might have the same problem. The brand's "Hungr.AI" campaign, launched September 1, 2026, reframes AI hallucinations, bizarre answers, and overly agreeable responses as something familiar - maybe the AI is just hungry.
The idea extends the "You're Not You When You're Hungry" platform into a cultural conversation already happening around generative AI and LLM behavior. "Just like people, AI can sometimes act unlike itself and make humorous mistakes - confidently giving an incorrect answer, validating a bizarre idea, or being overly agreeable," said Ashley Gill, vice president of brands and content marketing at Mars.
Those peculiar AI behaviors looked suspiciously similar to the way people act when hunger takes over. "If hunger can make people act unlike themselves, we can have a little fun when AI starts doing the same," Gill said.
The films: marathon advice and tattoo placement
The campaign includes two films directed by Pete Marquis through Good Behavior. "Marathon" shows artificial intelligence encouraging someone to attempt a marathon without training. "Tattoo" finds another user entertaining questionable placement advice. Both are absurd, but only slightly more absurd than actual AI interactions circulating online daily.
Josh Gross, chief creative officer at BBDO Chicago, said the opportunity came from recognizing how neatly AI's occasional odd behavior fit the brand's existing premise. "The great brand platforms stay true and relevant no matter how much the world changes around them," Gross said. "Once we realized AI's weirder habits are actually quite comparable to hungry human behavior, we couldn't resist bringing 'You're Not You When You're Hungry' into the conversation."
Feeding AI a digital SNICKERS
The creative question became: how exactly do you feed artificial intelligence a SNICKERS? The answer is Hungr.AI, a digital SNICKERS bar users can paste into an AI assistant when it begins dispensing questionable advice. The experience incorporates humorous prompts designed to "feed" the AI and steer its response toward something more useful.
Mars is careful about the claim. "There is functionality behind the experience, but we're not claiming that SNICKERS is literally fixing or improving AI tools, and we are not a tech company," Gill said. The joke works precisely because it doesn't need to. AI hallucinations and overly agreeable assistants have become recognizable enough that the behavior already feels relatable.
A brand platform that bends without breaking
Rather than attaching SNICKERS to artificial intelligence simply because AI is the technology of the moment, BBDO Chicago found a behavior that genuinely fits the existing brand platform. "The opportunity isn't simply to put SNICKERS into a new technology conversation," Gill said. "It's to take a real, relatable conversation people are already having and give it a distinctly SNICKERS spin."
That distinction matters. Plenty of brands have spent years asking how to incorporate AI into their advertising. SNICKERS found a better question: what if AI already behaves exactly like a SNICKERS commercial? The platform, which debuted during Super Bowl XLIV in 2010 with Betty White, still has flexibility. The faces, situations, and technology can change completely while the basic insight remains intact. Someone, or now something, starts behaving strangely. There must be a reason. Give them a SNICKERS.
Why this matters for creatives
The campaign demonstrates how a durable creative platform can absorb new technology without becoming a gimmick. BBDO Chicago didn't force AI into the work - they recognized that AI's documented quirks already mirrored the brand's central joke. For AI for creatives, the lesson is not to chase technology for its own sake, but to identify where genuine cultural behavior overlaps with an existing brand truth. When the fit is real, the audience doesn't need the joke explained. They already live it.
