I've never blanked out in public before.
But i've blanked out NYE 2005. I started calling people all over
the world and rambling crap. I think a few people here got my phone
calls too. 
And i must say... i blanked out totally for about 45 mins. I've
lost it. No idea what i did, what i said. But it was in a safe
environment at a friend's place with only 4 of us.
Another time... we got sloshed as heck on too much champagne
cocktails and everyone went skinny dipping....during a cold night
5am at your boyfriend's parents house is not a good idea. We were
all above 25 and getting told off by his dad.... who walked out
when my gf was passing out naked on the decking. AHHAHHAHA Anyway
point is, i have worst pics than those of people drunk. However i
and i hope my friends would never do that in public. Or have pics
taken by strangers where you have no control over.
