The green thing is a shower cap! The first game someone had to wear a mullet wig, last game someone played with a sleeved tattoo (although that was a bit lost on our team as they are full of real ink!) and this week it was a shower cap. Joffa does some secret service thing with names etc and I think he pulls one out of a hat and that player has to be the one to wear the designated joke that week.
First time North Croydon have ever been beaten!!! Well done, old timers!
