Why don't you just tell them that the banner you are holding is actually not technically in your possession since although you appear to be holding it you actually transferred ownership of it to another person who looks a lot like you and lives in the same house but who is not presently in a ground that requires fire certificates.
Or just tell them it's a big handkerchief.
I'm surprised you haven't been battered by the Pro-SISU band yet and i'd be more impressed if you managed to get an image of the enigmatic Joy Seppala to go on it...... whoever she is...........
All joking apart, this has to be the end of SISU at our football club.............If we have a scenario where they've srewed this season up and we receive points docked next as well and they are still clinging on playing their games and spouting rubbish then the clubs support will melt away to next to nothing. I really hope that they know they have to go !
