Several people are asked to prove that all odd integers greater than 2 are prime.

- Tenured mathematician: 3 is prime, 5 is prime, 7 is prime, 9 is not prime. Ha! A counterexample.
- Untenured mathematician: 3 is prime, 5 is prime, 7 is prime… so by induction, all subsequent odd integers are prime.
- Statistician: Let’s verify this sone several randomly selected odd numbers, say, 23, 47, and 83.
- Computer scientist: 3 is prime, 5 is prime, 7 is prime, segmentation fault?
- Computer programmer: 3 is prime, 3 is prime, 3 is prime, 3 is prime…
- Physicist: 3 is prime, 5 is prime, 7 is prime, 9 is an experiemntal error, 11 is prime…
- Mechanical engineer: 3 is prime, 5 is prime, 7 is prime, 9 is approximately prime, 11 is prime…
- Civil engineer: 3 is prime, 5 is prime, 7 is prime, 9 is prime…
- Biologist: 3 is prime, 5 is prime, 7 is prime, 9 is… still awaiting results…
- Psychologist: 3 is prime, 5 is prime, 7 is prime, 9 is prime but suppresses it, 11 is prime…
- Economist: 2 is prime, 4 is prime, 6 is prime…
- Politician: Shouldn’t the goal really be to create a greater society where all numbers are prime?
- Sarah Palin: What’s a prime?
