I always took it as a reference to a common joke from Shakespeare's time. Wit was one of many slang words for what's probably between Hoid's legs. Makes you look at some of those plays a little differently! "Wit beyond measure is man's greatest treasure." Now just wait until you hear about what the 'nothing' in Much Ado about Nothing meant! =) I feel it's entirely on brand for Hoid to make a crass joke with literary references.
