Mathematicians Demand Mathematical Foundations

Mathematicians when you say “2+2=4” without first defining the Peano–Dedekind axioms and ontological legitimacy of numbers as an equivalence class of cardinalities under bijective mappings:

A stark black-and-white close-up of a stern bald man appears beneath a caption mocking mathematicians who overcomplicate the statement that two plus two equals four. The joke references formal arithmetic, Peano–Dedekind axioms, ontology, cardinality, and bijections, portraying an absurdly intense reaction to a basic fact.
