You end up discussing economic policies with a stranger and everyone around looks at you like there's something wrong with you for speaking of such things in public.
When I get really drunk I get on public transport and fake like I am talking in a cell phone pontificating my opinions on abortion, God and the Middle East. It is either that or drag race in a Hyundai Getz.
When I am drunk I also get on public transport and pretend I am speaking in an ear piece, I then stare at suspicious looking people and say things like "The Eagle has landed, I repeat, the Eagle has landed."
