Oh man this thread is too funny! 

However I could see someone running an extension cord from the neighbor's house. I would bet money we see that in a news article within the next year. Expanding on that I could see someone in an apartment building cutting holes in the drywall and tapping into the neighbor's electric from the back of the wall.

I bet some jail time would be attached to that. "Theft of services" I believe is the correct term.
