- The Merch: Plenty over the years, besides the products being promoted, but especially notable in what they sell at their M&M's World stores in New York, Las Vegas, and London.
- No Export for You: Ads with characters other than Red and Yellow very rarely make it to the United Kingdom for some reason.
- The Other Darrin: Originally, Red and Yellow were voiced by Jon Lovitz and John Goodman, respectively.
- Pop Culture Urban Legends: It was wildly believed that Blue was originally voiced by Phil Hartman, and that Robb Pruitt replaced him after his death. However this interview with Robb reveals that he was always the voice of Blue.
- What Could Have Been: Steven Spielberg approached Mars to have M&Ms be the candy that E.T. would munch on. They declined, not thinking the movie would be big enough to move their product. Spielberg then made the same pitch to Hershey, who accepted, and the movie single-handedly put their Reese's Pieces on the map.
