- Defictionalization: "green, egg and ham" was a real dish, but the "green" referred to a vegetable side dish rather than the color of the meal as a whole, hence the joke. While the real dish has fallen out of favor, actual dishes of green eggs and green ham, however, have cropped up as references to the book:
- The Friendly Toast, a breakfast joint in Portsmouth, NH (with a second location in Cambridge, MA) is one of the more famous of the Greasy Spoon-type places that actually make their own version, though the ham isn't usually dyed green.
- In 2012, as part of promotion for The Lorax movie, International House Of Pancakes offers Green Eggs and Ham, mixing spinach with scrambled eggs.
The animated version
- Actor Allusion: When the nameless guy eats the green eggs and ham and likes it, he lets out a "Hoo-hoo-hoo-hoo!" See Hey, It's That Voice! below.
- Hey, It's That Voice!: Paul Winchell voiced both of the main characters, with the big guy sounding a lot like Tigger (especially apparent near the end) and Sam-I-Am sounding like Dick Dastardly. In other words, Paul Winchell was having one long conversation with himself.
- Talking to Himself: Both Sam-I-Am and the nameless guy are voiced by Paul Winchell.
