Greater fool theory

The greater fool theory (sometimes the bigger fool theory, also called survivor investing) is the belief held by one who makes a questionable investment, with the assumption that they will be able to sell it later to "a bigger fool"; in other words, buying something not because you believe that it is worth the price, but rather because you believe that you will be able to sell it to someone else for an even better price.[1]

Finnegans Wake

Finnegans Wake is a work of comic fiction by Irish author James Joyce, significant for an experimental style and its resulting reputation as one of the most difficult works of fiction in the English language.[1][2] Written in Paris over a period of 17 years, and published in 1939, two years before the author's death, Finnegans Wake was Joyce's final work. The entire book is written in an idiosyncratic language, consisting of multilingual puns and portmanteau words, which attempts to recreate the experience of sleep and dreams.[3] Due to its expansive linguistic experiments, stream of consciousness writing style, literary allusions, free dream associations, and its abandonment of conventions of plot and character construction, Finnegans Wake remains largely unread by the general public.

Egg of Columbus

Columbus was dining with many Spanish nobles when one of them said: 'Sir Christopher, even if your lordship had not discovered the Indies, there would have been, here in Spain which is a country abundant with great men knowledgeable in cosmography and literature, one who would have started a similar adventure with the same result.' Columbus did not respond to these words but asked for a whole egg to be brought to him. He placed it on the table and said: 'My lords, I will lay a wager with any of you that you are unable to make this egg stand on its end like I will do without any kind of help or aid.' They all tried without success and when the egg returned to Columbus, he tapped it gently on the table breaking it slightly and, with this, the egg stood on its end. All those present were confounded and understood what he meant: that once the feat has been done, anyone knows how to do it."
