Step 1: construct hollow false hand to resemble your own hand, with threaded removable thumb.
Step 2: remove own hand (preferably non-dominant hand).
Step 3: replace real hand with hollow replica, fill with alcoholic beverage of choice, enjoy public consumption of alcoholic beverage of choice.
Or, for those who prefer not to do it themselves (or do not own a chainsaw)...
New from Alterorder, Inc.: the Handy-Flask!
Please include sample hand with completed order form to ensure proper fit and realistic appearance.-- Alterother, Oct 04 2011 A dripping slap on the back [+].-- swimswim, Oct 04 2011 + cute, but I just drink alcohol in a MacDonald's cup...-- xandram, Oct 04 2011 I just drink at home, but for some people that's too simple a solution...-- Alterother, Oct 04 2011 I think the warning about which hand to choose should be moved to step one, otherwise you'll be identify the people with two right hands as likely covert alkys.-- pocmloc, Oct 04 2011 <ponders transexual flask> ...-- FlyingToaster, Oct 04 2011 Why on earth would anyone want to use this? You would forego the uber coolness of being the rugged and shifty fellow in the back of the no-name diner, surreptitiously tipping up a brushed steel flask, under the table to "irish up" his cup of joe.
[+] anyway, but I prefer my method.-- MikeD, Oct 04 2011 Hey, I'm just responding to a market. If people want to pay to have their hands chopped off and replaced with non- functional replicas designed to conceal a few ounces of booze, who am I to question their motives?
I'm [The Alterother], that's who.-- Alterother, Oct 04 2011 Couldn't it just be sold with a coat with one sleeve what is longer than the other?-- nomocrow, Oct 05 2011 No, you're totally missing the point. That would make the amputation completely unnecessary.-- Alterother, Oct 05 2011 random, halfbakery
