I had a great time, and the costumes were great. I also really really really liked Pete's StrongBadPumpkin!!!!!
I came partially out to my brother, and he seemed to take it well.
The A/V portion of the party worked perfectly.
So, in summation, party good, me drunk, unhealthy food mostly gone.
I am currently drinking v8 to rehydrate while I sober up.
Life is good right now.
