The laundry room sink. The most oft-nudely-climbed window in Risley. It's especially nice when you're watching from Pool and there's just this perfectly-framed, backlit ass in the window with steam rising from it. Some Risleyites bear proud scars from the sharp edges (though it's hard to hurt yourself when sober).

Climb out of the sink.
Adjust the water temperature and jump back into the courtyard.
