!! The book

* {{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 GreasySpoon-type places that actually make their own version, though the ham isn't usually dyed green.
** In 2012, as part of promotion for ''WesternAnimation/TheLorax'' movie, International House Of Pancakes offers Green Eggs and Ham, mixing spinach with scrambled eggs.

!! The animated version

* ActorAllusion: When the nameless guy eats the green eggs and ham and likes it, he lets out a "Hoo-hoo-hoo-hoo!" See HeyItsThatVoice below.
* HeyItsThatVoice: Paul Winchell voiced both of the main characters, with the big guy sounding a lot like [[Disney/TheManyAdventuresOfWinnieThePooh Tigger]] (especially apparent near the end) and Sam-I-Am sounding like [[WackyRaces Dick Dastardly]]. In other words, Paul Winchell was having [[TalkingToHimself one long conversation with himself.]]
* TalkingToHimself: Both Sam-I-Am and the nameless guy are voiced by Creator/PaulWinchell.
