A friend from Pennsylvania forwarded this Craiglist job ad. If you're interested, hurry before it expires. So many questions: What is the business in June 1983? Perhaps a modest investment in Apple Computer. The need for a cat sitter could be avoided by returning on the same day, but perhaps time that passes in the past must be accounted for somehow. A two-day job, then. I have to assume "circumference" of the head was intended. The average circumference of the human head is reportedly 57 cm, based on a Web page I pulled up at random. Do you have to climb through some kind of porthole? Or wear a special helmet? Will you have to lift the time machine? Perhaps to hide it.

Seriously, though, most cats can get through a couple of days alone with a bowl of dry food and water.

Update: There is a similar time traveler ad meme / prank out there, which has now inspired a movie, "Safety Not Guaranteed."
