Eric Cantona
Proof of what a cultured bunch we Arsenal fans are.

When Eric Cantona played for Man United, their fans would often come out with the chant, "Ooh-Ah Cantona!, Ooh-Ah Cantona!"

So when they played Arsenal at Highbury during the time he was banned from football after his kung-fu kick at a Crystal Palace fan, I started off a chant, to the same tune, of "Ou est Cantona? Ou est Cantona?".

It ended up with the whole Clock End singing it, barring some very pissed off Man U fans who were probably upset all the way back home to Surrey, and a mention in the following day's paper.

A mate
tried to start a chant at Hitchin Town FC. It went:

One referee
There's only one referee
There's two linesmen
But only one referee

It didn't catch on.

My mate Ken tried that one too
Still didn't catch on

Excellent news
I was worried that he had thought of it himself which would make him annoyingly clever.

Turns out already bindun
I did a quick Google on "ou est cantona" and it turns out pretty much every side's supporters came out with it at some point (Chelsea to Leeds after he went to Man U, West Ham to Man U after he retired). Oh well.
