This is the 1729th time I've heard a form of this joke just in the past year.

Hey, I just noticed something. 1729 is the smallest positive integer that can be written as the sum of two cubes in two different ways.

6^3 + (−5)^3 = 216 + -125 = 91

4^3 + (+3)^3 = 64 + 27 = 91

1^3 + (-1)^3 = 0

0^3 + (-0)^3 = 0

^_^

Zero isn't a positive integer.

I noticed that property when I was 10 after the schoolmaster forced the class to write out the cubes of 1 to 20 to keep us quiet for a few hours.

Oh yeah? Well, I noticed it when I was five, because I'm just naturally gifted.

I'm an inside joke detection prodigy. Something is off here.

That's okay - since you are still around you can split it into multiple comments. We'll wait :)

I bet your proof is truly marvellous, though.

Could you please show the proof
