I was working a club in Essex once and we were confronted with a guy who was waving a gun in our direction screaming blue murder because one of us had thrown him out, we all realised it was a replica because we already knew of this idiot and knew he was a bit of plastic gangster. One of the guys I was working with that night, walked up to him, slapped him about a bit before giving him the obligatory farewell speech and taking the gun off him.
Our mate walked back to the rest of us with the offending article....and yeh you guessed it....it wasn't a replica....do'h....
I think we all begun laughing when we realized but I am also pretty sure there were a fair few 'emptying of the large colons' as well....
