Frank Gehry's 72K dollar fish lamp  

Nothing should be worth that...
Nothing should be worth that much....nothing. Well, maybe a small house or nice car;)

And...?
There's lots of expensive art for sale in the world; is there something particularly noteworthy about this piece?

Noteworthy
only in the fact that I can think of dozens more venues other than ebay to try and sell a 72K lamp to a very select market.

Look at the feedback
Hasn't sold a bloody thing in years!

Art dealers can wait forever...
Art dealers can wait forever for consigned pieces to sell. Doesn't cost them anything.
There's a Warhol print, for instance, that's been on Ebay for over a year. Even if it never sells, it makes money for the dealer: Some percentage of the people who see it also look at his other items and end up buying a $100 Peter Max poster or an $8000 Keith Haring print or something.
Interestingly, the dealer keeps tweaking the Warhol's auction text. Every couple weeks, he changes something -- the title, the subtitle, a few words in the description, even the shipping terms -- as though he actually expects to find the magic phrasing that'll induce someone to mail him $100K+.

That lamp
either makes me sick or hungry.
