Gentlemen, my apologies, I was being facetious.

I need to direct you to an earlier uk.D-I-Y thread entitled "Blowing
Neighbours smell away" (posted 27/08/2011), and in particular to the rabid
defence of an anti-social habit by "The Medway Handyman", who is the OP for
this thread.

Considering the nature of the addiction, it seemed obvious why TMH was
considering the purchase of a borescope ;-)
