Inspired by the Windows Mobile advert which always makes me laugh.
Here are the details:
It's a wall mounted unrinal, so you don't have to bend down to your feet to get it.
You've ceased pissing, so there's no flow to contend with.
There are no major drainage issue to contend with, so the urinal is mostly piss free.
It also contains one piece of chewing gum, and half a urinal cake (lemon).
The phone is your phone.
Feel free to alter these to adequately express your willingness to root around in piss.
