Gary Marcus's favorite science joke

An interviewer approaches a variety of scientists, and asks them: "Is it true that all odd numbers are prime?" The mathematician rejects the conjecture. "One is prime, three is prime, five is prime, seven is prime, but nine is not. The conjecture is false." The physicist is less certain. "One is prime, three is prime, five is prime, seven is prime, but nine is not. Then again 11 is and so is 13. Up to the limits of measurement error, the conjecture appears to be true." The psychologist says: "One is prime, three is prime, five is prime, seven is prime, nine is not. Eleven is and so is 13. The result is statistically significant." The artist says: "One is prime, three is prime, five is prime, seven is prime, nine is prime. It's true, all odd numbers are prime!"
