If you wait outside one of the bars in a town at night... sometimes there is a drunk guy pounding back tankards of mead dancing and head banging, its pretty funny. I'm in Solitude right now and Octieve San is one of them.
In the future Bethesda should add drunken bar brawls and stuff and if you drink alcohol your character actually stumbles around and loses dexterity and vision gets blurry. They had something like this in S.T.A.L.K.E.R : Shadow Of Chernobyl.
