I like these jokes. Somebody says that published paper is a kind of currency in the academic world. Actually people write two papers per minintue in the natural science world, but they just read less than 1 percent of the papers published. They just want to publish a paper without nasty peer review. Assumption is the mother of all screw-ups.
Biologists think they're biochemists.
Biochemists think they're chemists. Chemists think the're physical chemists. Physical Chemists think they're physicists. Physicists think they're God. God thinks he is a mathematician.
