The daftest one I ever heard would have to be the Wiggy chant. Sung to the same tune as 'Wanky Wanderers', it was aimed at midfielder Nathan Wigg, and went "Oh Wiggy Wiggy, Wiggy Wiggy Wiggy Wiggy, Wiggy Wigg".

I had to rack my brain to work out that this chant (and others like it) are based on the song 'Son of my Father' by Chicory Tip. This dates its earliest possible outing to 1972, and it was still around while Wigg was at City, between 1993 and 1996.
