The Developer says:
“All odd numbers are prime”
“Let's see, 3 is prime, 5 is prime, 7 is prime - looks like it‟s true”The Project Manager says:
“Let's see, 3 is prime, 5 is prime, 7 is prime, 9 is prime, 11 is prime –looks like it‟s true.”The Tester says:
“That's silly, nine is a non-prime odd number - looks like it's bullshit”
I recently heard this very sad anecdote while attending a lecture about Software Testing.
Everybody (except maybe a Test Manager) knows the developer would look up prime numbers on google before even trying to answer.
Anyway - here's a good resource about odd prime numbers humour.
