No such thing as an ex Scummer. Once a Scummer always a Scummer, there is no redemption unless you score a hatrick against them and following the 3rd goal, kiss the Town badge - bare your arse at the Scummers and then smack a couple out. Althuogh the bit about baring the arse is obviously the riskiest bit in view of their proclivities.
Although he didn't quite do all of that, I think Wayne Allison managed to leave his scummy past behind...looked delighted when he scored against city.
