Guess what this is?

You have to love radiologists and MR physicists. I ask them, "Where is the ladies room?". They point me down the hall. All I see is the door to a 4 Tesla magnet (pictured above) and an elevator. So I go wandering around until I do find a ladies room. Later as we were being escorted out we walked past the door again next to the elevator and it was then that they pointed out that this is in fact the water closet and not the MR closet. They decided to playfully relabel it.
