Things I have in my room, which sum up a lot of my personality:
The usual furnishings. My TV and DVD player are perfectly positioned to watch from the sweet sweet comfort of Bed. My desk is too full of crap to actually be useful. My chair was stolen from a skip in Leeds city centre when Mecca Bingo were being refurnished. It was on the top of a pile of nice clean chairs though, so I don't know why they bothered throwing them out. Waste.
I have an excellent quality hifi which can hold 5 CDs. This suits me cos I'm too lazy to get up to change discs. Most of my CDs are dance compilations - trance or funky house.
A midi keyboard. But I'm not very good.
Posters of... Captain Jack Sparrow, Stewie Griffin, Homer J Simpson, Gorillaz, The Bunny Suicides, Ross Noble, Retarded George Bush quotes, Futurama.
Postcards from holidays in various parts of Spain.
A collection of badges which are stuck to the wall. Including such classics as "Vince Noir ate my cat", "Chuck Norris can divide by zero" and Dr Zoidberg's face.
A picture of a cow eating some snails.
A Jesus figurine, complete with posable arms and "gliding action".
An extensive collection of take-away menus.
A fantabulous selection of british comedy genius in DVD form. (Dylan Moran, Bill Bailey, Dara O'Briain, Father Ted, Black Books, Ross Noble etc.)
A battery operated, walking cuddly pig.
A drawer full of stripy, checked, patterned or otherwise mildly interesting socks. Actually there are a few drawers.
Some neuroscience textbooks which cost far too much money to say they rarely get used and often live on the floor under several layers of Stuff.
Piles of dirty washing, and piles of clean washing. This sometimes leads to confusion.
Printouts of Dilbert comic strips stuck on the walls.
Every Harry Potter book, all of Terry Pratchett's Discworld series and The Hitchhiker's Guide.
