I also think this changes depending on the job you're going for. There's absolutely no reason I'd try to be funny or interesting on my entry-level order picker job. Assuming they even bother to look at my CV they're mainly looking to see if I've got any work history.
If I'm applying for something creative, or maybe something that requires a bit of personality I'm sure it'd go over better... although even that is a double-edged sword.
