Two Showerheads Are Better Than One

So as you know, I'm in Boston this week for a work conference. I bitched yesterday about the state of my 'Artic Suite' of a hotel room...however, what I neglected to highlight, and didn't learn about until this morning, was the awesome and somewhat non-sensical 'dual showerhead' in the bathroom. Yes, we've all heard of dual showerheads before..typically either a shower head at each end of the shower to get 'back to front' action or to share with a 'friend' or even the dual showerheads where one is in the traditional position on the wall in front of you and the other overhead like a 'rain water'...well, this was neither....

HUH?
