What is the Silliest Accessory You Have Ever Seen.

I think it would cost more to keep a patent pending for 17 years given than it would cost to simply file it.  I am guessing that patent application is long since not pending.

In descending order of ridiculousness, proportional to its price:

- cable lifters
- boutique fuses
- power cables
- digital cables

The green pen for coloring the edges of cd’s..

Green cartridge stylus paper. Used in the 80’s to disastrous effect by most. Either blunted styli or alternatively sharpened them to a lethal point.

@audio2design, the first denial would come in about 6 months usually stating "Prior Art." To keep it going for 17 years with lawyers would cost a fortune but I am almost sure the patent office would offer a final denial after they had had enough. 
@grannyring , there is a sucker born every minute and they are the fish these hoodlums' feed on. If you do not know enough to make an intelligent decision ask someone who is. When humans are involved it is always best to doubt everything.
@pokey77 you have to be kidding. I have decided I'm going to make my fortune creating a string of companies that make nothing but audiophile absurdities. You have convinced me there is a growing market for such things. If they can get daveyf for $1500 I bet I can get him for at least $2500. I'll start with a full system demagnetizer (just a fancy power strip you plug all your stuff into) and follow it up with the Phonograph Holographer ( a little box you plug up between your phono stage and preamp, gives you a holographic sound stage.) Next, lets see...ah! The Image Synthesizer, a triangular wooden box 6 feet tall you put in-between your main speakers. Prevents that hole in the middle. It will all work. I promise! Such is the power of psychoacoustics.
