A work of great literature by Dr. Seuss, originally published in 1960.
The tale is simple: a person named "Sam I Am" tries to persuade some sourpuss to eat Green Eggs and Ham.
"I will not eat them on a boat! I will not eat them with a goat! I do not like Green Eggs and Ham! I do not like them, Sam I Am!"
But Sam I Am persists, and eventually, the sourpuss relents and tries a bite. He loves them and proclaims that he will eat them all the time.
The book remains one of the most popular children's books -- both with kids and their teachers -- in history.
