To the list of oeuvres d'art mentioned in the article we should add 'My Bed' by Tracey Emin, which features an unmade bed with grubby sheets, surrounded by condoms, soiled knickers and bottles of vodka, and was shortlisted for the £20,000 Turner Prize. A good friend of mine has a bed like that, but no-one's offering him 20K.
I'd be too timid to admit that. (LOL)
