"Do you move through the bar with a glass in your hand, thinking too hard about the way you stand"

Firstly Elbow are absolutely fantastic, perfect for revision, perfect when you want to chillout, perfect pretty much anytime. Seems a long time ago that I saw them in Cornwall (I actually can't remember what year it was, hingley... 2002?) but they were good then not brilliant, but awesome when I saw them a few months ago. If you haven't ever given them a go then do because well they rock.

Secondly, those things in urinals, the plastic things that well I guess stop the yellow things going away, I dunno how better to explain them. Anyway the ones in the Notts uni bar are made by "swisher" (I think, unless that is what they are called I dunno I didn't really want to examine it any closer, plus the guy on my left may have wondered what I was doing) I was wondering:

a) who first umm invented them?
b) why? They seem pretty redundant and well if I was an inventor I don't think that would be the first major improvement I would come up with, maybe that's why im not an inventor.

I also want to know if "swisher" have a monopoly on it, are they the only company swamping the urinals with this pretty useless thing. I apologise if in fact they have a virtue which I haven't noticed. So do other people's unis/work places etc have the same manufacturer? I'm going to check in Birmingham for sure.

Anyway I am going to watch the football.
