The Greek Philosophers

There's a story I'm rather fond of about Greek Philosophers. It goes thus:

Three Greek Philosophers are dining at a roadside inn and arguing about how many teeth a horse has. The first one opines that it's 32, the second 34 and the third 36. They argue and argue as the wine is consumed, each coming forth with mathematical proof of why his and only his answer is the correct one.

Eventually, tiring of the argument, they beckon to an Arab sitting at the next table and ask that he hear each argument in turn and judge who is correct. The Arab listens patiently to each argument then says 'wait a moment gentlemen' and disappears. He returns a few minutes later and points to the third greek. 'You, sir, are correct'.

Although satisfied that the argument is finally over they want to know what abstruse reasoning the Arab used to determine the correct argument.

'Simple, sirs' he replies. 'I went out to the stables and counted them'.

You probably don't remember that I wondered what MET CUST WOM[^] meant, in the context of UPS parcel deliveries. Today I finally remembered to apply the Arabs method as I found myself sharing the lift at the office with a UPS guy who had nothing better to do as we descended 8 floors. So I asked him.

It turns out that, just as 'Anonymous' responded on the earlier post linked above, it means it was delivered to a woman at the target address.

How disappointing that it's such a prosaic meaning!
