He can't delete it for a few reasons, some of which may be...
1) Having the icon there maintains a sense of purity in the OS; that is since the Mac OS X installer places it there after a fresh install... it is sort of like an air freshener with that 'new car' scent.
2) He really digs the way the icon looks, even though he will never click it. Copying that icon onto another URL just wouldn't be the same.
3) He has a fetish for springs. I've seen British porn, you people are just as kinky as Americans
4) He fears that as soon as he deletes it, he will for some reason either need the icon or need to click it.
