If you have one post it here.
I'll start:
My theory, since it is a topic everyone loves, is about beer. I hypothesize that there is a higher concentration of alcohol in beer (as in most drinks) closer to the glass than in the drink itself. My reasoning is thus. Glass is mainly composed of silica (75%) and as such is mainly non-polar. The majority of the ethanol molecule (or rather the alcohol in "booze") is an alkyl group which is also non-polar. In chemistry, like attracts like so the alkyl chain portion of the ethanol molecule should adhere to the surface of the glass. This would mean that the majority of the glass should be coated by alcohol. Now since the rest of the molecules not adhering to the glass should be governed by the rules of molecular diffusion, the rest of the alcohol is distributed evenly in the drink. But since there may be a higher proportion of alcohol is on the glass, make sure you lick your glasses after drinking to make sure you get wasted.
