or how logic can lead one astray.
Reported on that inestimable educational programme QI, the Greek philosophers explained the purpose of the male dangly bits thus:
Because people without said appendages, or with small undeveloped dangly bits have high pitched voices.
And people with large, pendulous dangly bits have deep voices, the purpose of said family jewels was to tension the vocal chords, thereby changing their pitch.
Isn't logic wonderful?
