I have seen it and the keeper was taking the piss.
It is one thing Dunky standing on the ball to draw out attackers, but you can't do this with a dead ball, which it is by default (as it is untouchable when in the keeper's hands). Once the keeper has put the ball on the floor it is live again...
I owe you an apology. This comedic device was stolen from the pages of Private Eye. If you are unfamiliar with it, it may seem odd. I refer you to my strapline :wink:
