!! The book
* BeamMeUpScotty: One of the lines in the book is often quoted as "Would you eat them in a house? Would you eat them with a mouse?". The line is actually "Would you '''like''' them in a house? Would you '''like''' them with a mouse?".
* {{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 2008 and 2012, as part of promotions for the ''WesternAnimation/HortonHearsAWho'' and ''WesternAnimation/TheLorax'' movies, International House Of Pancakes offers Green Eggs and Ham, mixing creamed spinach with scrambled eggs.
** In addition, green eggs were annoyingly common in early Army rations. The sulfur in the eggs reacted with the preserving process, turning the eggs an unpleasant shade of green. The taste wasn't affected, but visually, more than a few soldiers found them disgusting.
* FanNickname: Some unofficial sources call the other character, "Joey".

!! The animated version

* TalkingToHimself: Both main characters are voiced by Creator/PaulWinchell, making the whole short feel like a conversation between [[WesternAnimation/DastardlyAndMuttleyInTheirFlyingMachines Dick Dastardly]] and [[Disney/TheManyAdventuresOfWinnieThePooh Tigger]]. There's even an ActorAllusion when the nameless guy eats the green eggs and ham and he lets out a distinctive "Hoo-hoo-hoo-hoo!" when he likes it.
