The parable of the *what*?

This morning, as I was reading in the Bible (in German), I caught sight of a subheading "Das Gleichnis vom Fischnetz" and mentally translated it as "The parable of the fishnets", and the image I had in my mind was of someone wearing goth legwear... rather bizarre. I blame the early hour.

(It's merely "The parable of the fishing net"; the t vs tz is a result of a regular sound change.)
