Worst: cliche, but, I had this awesome plan to collect taxes before update (defcon 5, no war improvs, all econ) at 5 minutes before update, then pay bills after update since that would be 3 days of no bill paying, and switch everything back by 5 minutes after update. I ended up not being able to purchase improvs because of those 3 days, and thus had no LC's, blowing a hole in my WC, with a net loss (3 days income - 3 days bills), instead of net gain.
Best: Agreeing to help Ogopo and jinger with SLCB. It's been an interesting ride since. Ah crap, I'm just full of cliches.
Best without cliche: Not posting in half of the threads about Stickmen, purple, the war, and 90% of all other threads on the OWF.
