I was walking back from a club just now and thought I would be nice and ask the guy leaning against a lamppost with his eyes closed if he was all right. Unfortunately this resulted in him saying the word "Chris" over and over and then walking slowly towards me. It was seriously like one of the zombie scenes in Shaun Of The Dead. I had to make a quick exit. Would hate to be him in the morning!
Moral of the story - helping drunk people is not worth the effort.
