The 'You're Not You When You're Hungry' campaign, launched by Snickers during Super Bowl XLIV in 2010, features celebrities like Betty White and Joe Pesci acting completely out of character due to extreme hunger. The campaign's core premise is that hunger transforms people into divas, complainers, or irritable versions of themselves, and only a Snickers bar can return them to their normal state. This relatable concept quickly transitioned from television screens to internet culture, where it became a massive phenomenon. The meme is now widely used to humorously explain irrational behavior, mood swings, or dramatic personality shifts, making it one of the most enduring commercial-based templates in social media history.
