The answer is surely in the question?

Not a chant, but the mass of red cards prepared by one esteemed member of the board to greet a visiting player at Headingley takes some beating.

Didn't that little jape make the YEP?

It wasn't too long ago since a large section of the South Stand and fans in other areas, were waving banners and chanting 'Hetherington out!'

Anyone remember chanting along to this ?

My favourite was a couple of seasons ago when the mighty Cas were thumped the previous weekend at home by Warrington and we were due to play them on the Friday night and it was to be the SKY game that weekend. As SKY feared another thumping they changed games at the last minute.

When Cas ran out for the match they were greeted by 'You're too $h1t, you're too $h1t, you're too $h1t for SKY TV, you're too $h1t for SKY TV!'

We were in our seats for Quins vs Dragons game and none of you there

Not sure, but it was in the League Express.

So I'm told.

I would like to see the Hey McBanana song manifest next season!

Not a song as such but I was once stood next to a bloke who had his pipe out and was spinning it round (I believe it is called windmilling) and it made a really good whooshing noise as it span through the air.

I was, and I was sat surrounded by Saints fans for the game

i'd keep that to myself if i were you

"you're not Gateshead anymore"
To Hull FC in response to "you're not singing anymore"

"Marcus Bai-sexual"
(tune of F*ck Off, Mourinho) when he was at Bradford

That was a great night IIRC didn't he get sin-binned in the second half and jim fallon going over for the winning try!
Happy Days.
