At university, we over heard a friend of mine singing along to Boy George's "Karma Chameleon" - except she was singing "Come-a, come-a, come-a, come-a, come-a to me, Leon". Which, when you consider that that phrase is the title of the song, is pretty bad. Earlier that term she had cut herself with a spoon. Enough said.
