Trajan: I prefer things like putting fish and/or cheese (particularly limburger) inside the AC vents.
As for what to FTP home, I'd go for accounting records, customer lists, anything marked "Proprietary", and (if possible) anything in the CEO's personal folders. Oh, and the bookmark list from your web browser. Then:
- Give the accounting records to the IRS and SEC
- Use the customer lists to build your own business (possibly with the other fellows who preceded you onto the "dole")
- Sell the items marked "Proprietary" to your (former or soon-to-be-former) company's competitors
- Look for blackmail material in items from the CEO's personal folder
- Import your work bookmarks into your home bookmark list (obviously, this is my only constructive suggestion; the rest are rather... destructive)
Of course, if you're caught doing any of those things, the agency will disavow all knowledge of your activities. This post will self-destruct whenever the Cantina blows up again...
