CNET has a story of a guy who lived in AOL’s headquarders) after a startup incubator program he participated in ended. Eventually, he got caught but how he managed the was rather ingenious:

"Having spent several months legitimately working in the building, often quite late, Simons had noticed that although there were security guards with nightly rounds, there were at least three couches that seemed outside those patrols. Plus, they looked fairly comfortable. He claimed them.

This was his routine: He’d work until midnight or later, and then fall asleep around 2 a.m. on one of the couches. At 7 a.m. – and no later than 8 a.m. so he’d be safely out of his field bed before anyone else arrived – he’d wake up, go down to the gym for a workout and a shower, and then go back upstairs and scarf a breakfast of cereal and water or Coke. Then he’d work all day, finally waiting until everyone else in the building had gone home before returning to one of his three favored couches."

I’ve always wondered if that kind of thing could be pulled off. I guess so… for a while.
