Parallel postulate Memes

The first four postulates? Pure geometric bliss. Connect two points? Sure! Extend a line? No problem! Draw a circle? Easy peasy! Right angles being equal? Duh! But then Euclid drops his fifth postulate—that parallel line nightmare about inner angles and inevitable intersections—and suddenly our cartoon friend's brain short-circuits. It's the mathematical equivalent of hearing "the mitochondria is the powerhouse of the cell" four times and then getting hit with the entire biochemical electron transport chain explanation. Even 2300 years later, geometry students are still making this exact face when the parallel postulate enters the chat.
