3 is prime, 5 is prime, 7 is prime, and by induction we have that all
the odd integers are prime.
3 is prime, 5 is prime, 7 is prime, 9 is an experimental error...
3 is prime, 5 is prime, 7 is prime, 9 is prime...
3 is prime, 5 is prime... hey, let's publish!
Modern physicist using renormalization:
3 is prime, 5 is prime, 7 is prime, 9 is ... 9/3 is prime, 11 is
prime, 13 is prime, 15 is ... 15/3 is prime, 17 is prime, 19 is prime, 21
is ... 21/3 is prime...
All numbers are equally prime and non-prime until observed.
3 is prime, 5 is prime, 7 is prime, and the rest are left as an
exercise for the student.
Let p be any prime number larger than 2. Then p is not divisible by 2,
so p is odd. QED
There are exactly as many odd numbers as primes (Euclid, Cantor), and
exactly one even prime (namely 2), so there must be exactly one odd
nonprime (namely 1).
3 is prime, yes it is true....
10 is prime, 11 is prime, 101 is prime...
3 is prime, 5 is prime, 7 is prime, 9 will be fixed in the next
03 is prime, 05 is prime, 07 is prime, 09 is really 011 which everyone
knows is prime, ...
What's a prime?
What's an odd number?
3 is prime. Wait...
Now why would anyone want to know about that? That's not user
friendly. You don't worry about it, we'll take care of it for you.
1. No one will ever need any more than 3.

Software tech support operator:
Well, we haven't had any reports of composite odd numbers... do you
have the latest version of ZFC?
1 is green, 2 is blue, 3 is orange, 4 is red...
Hypothesis: All odd numbers are prime
1. If a proof exists, then the hypothesis must be true
2. The proof exists; you're reading it now.
From 1 and 2 follows that all odd numbers are prime
3 is prime, 5 is prime, 7 is prime, 9 aaah. I can make 9 a prime.
Why don't we just call all the odd numbers prime and call all the
prime numbers odd, that way all the odd numbers would be prime
3 is prime. Hum, that's an interesting statement, I'll get one of my
research students to look into that.
Assume 9 is prime...
2 is a prime, 4 is a prime.
2 is even, 4 is even, 6 is even...
3 is prime, 5 is prime, 7 is prime, 9 is not prime. Look, the prime
rate is dropping.
100% of the sample 5, 13, 37, 41 and 53 is prime, so all odd numbers
must be prime.
3 is prime, 5 is prime, 7 is prime, 9 is an outlier, 11 is prime, 13
