Not a patch on Crystal Palace (sorry Seagull) v Fulham in 1978 (?) when the referee blew about 6 minutes early with the error only being spotted after the players had all left the pitch. After a few minutes they had to return to play the final 6 minutes. However Seagull, you'll be pleased to know that despite the additional stoppage, Fulham held onto their 1-0 lead to win.
