A profound sense of something or other

Talking of mysteries, have a look at this, not a hardship if you are as dazzled by the female form as I am, though in this case I would like you to stop looking at their lovely legs and concentrate on the following little puzzle:

Labelling them 1 to 6 from left to right, put them in order of their weight from lightest to heaviest.

Ok, ok, you're smart and you smell a trap, the sort that QI indulges in. And you are right: these splendid ladies, despite appearances, are all the same weight, 154 pounds imperial.

Does that amazing revelation not give you a profound sense of something or other? In my case, it's the other.
