I was at a hotel and my laptop detected a network called "masturbationstation"
*EDIT* On a somewhat related topic, an old friend of mine used to take a netbook to Starbucks or the mall or something like that and create an open wifi network called "Starbucks free wifi" or something to that effect and had it set up to redirect users to a login page, like hotel wifi and other free wifi networks sometimes do, but the page instead had a message claiming that the person's device had been hacked, and had an animated gif with a progress bar slowly progressing with the label "downloading your personal files..."
He got a kick out of watching people slam their laptops shut.
