How about a Makinon 135mm f/2.8 with Macro Focussing? Is that wierd enough?
I am giving it away for shipping costs in the marketplace...and nobody wants it!
Here is what I wrote about it:
I got this lens with stuck, not sticky, aperture blades. I opened it up to clean, and realised I was out of acetone, so I cleaned what I could with a bit of alcohol and closed it up. The blades were now sticky, not stuck, and it could be used, mostly wide open. When I got acetone and tried to open it up again, I failed
So, if somebody wants to try to open it and clean up the blades, they are welcome to do so for the price of shipping. At the very least you can use it wide open. The macro operates by moving the front element forward; not the best method, but it's something.
I took a pic of my cute bears with it wide open, and I think they look pretty damn good (click through for a larger version):
