This is one of the 101 things - say, 101 is an interesting number, like 1729 - I learned about doin' science 'n' stuff.

*: Every number is interesting.*

**Claim***: There is a proof that every number is interesting.*

**Stronger claim***:*

**Proof**Consider the numbers:

- 0 is the unique identity operator for addition, which is interesting.
- 1 is the unique identity operator for multiplication, which is interesting.
- 2 is the only even prime, which is interesting.
- 3 is the first odd prime, which is interesting.
- 4 is the first square, which is interesting.
- 5 is the first Pythagorean hypoteneuse (2
^{2}+ 3^{2}= 5^{2}), which is interesting.- 6 is the first perfect number, which is interesting.
- etc.
- ...
Suppose we go on inspecting numbers, and we do eventually find a number that is not interesting. Why, that number would be the first non-interesting number, which is interesting.Therefore, by induction, all numbers are interesting. Q.E.D.

*:*

**Observations****1**. This is a (humorous & paradoxical) proof, or (what mathematicians call) an argument, but it is not a story.

**2**. Wikipedia says it is related to the Berry paradox.
