I was reading a thread where someone posted about the brown note and included this link:
http://en.wikipedia.org/wiki/Brown_note
at the bottom of the page, it talks about it's use in fiction and this is what they say:
In the show (southpark), the "brown noise" was described as "92 cents below the lowest octave of E-Flat", although the pitch sounded was actually F# (46.25 Hz).
now, the e flat part was part of the show's joke, but was the guy who "corrected" by saying f# just having fun with wikipedia, or was that actually part of the episode too?
