What is this?

This is an 18-SX entry... be forewarned. Ok, here's a quiz. Who can guess what this quaint little piece of object is?

Is it:

(A) Kristin's new necklace?

(B) A caterpillar with tattoos?

(C) Baby toy?

(D) Xmas tree deco?

(E) Ball-o-meter?

And the answer is: (E)! The Orchidometer, or Ball-O-meter, something I use frequently at work when evaluating hypogonadism. For such a simple device (string-of-pearls) it's bloody expensive.
