Obviously some kind of bi-valved apparatus from Audio Precision -- you've got to reach inside to flush it:

Nah!...those are ultra-modern transducers to ward off sonic pollution. They make sound come OUT of your ears.

 

[aptquark]

yea...I usually need the power of two flushes to take care of business...<cough>...

 

[sandbasser]

I give up, what is it?

Who took the top of their HATS (Head And Torso Simulator)? Those "handles" are the microphones that are mounted in the soft gel ears.

Yeah, but when you look at it quickly it looks like any other American Standard or TOTO porcelain fixture! I hope they don't take my analyzer away from me!
