Maid In The Shade
Megan McArdle on why hotels don't have zero-tolerance policies for guests who just happen to be naked when housekeeping appears:
...exhibitionists are careful to maintain plausible deniability [....] There are grey areas where we all know what's going on, but we can't prove it.
It reminded me of a Fred Willard line:
I was sitting naked in my hotel room when the maid came in...finally.
