At Maine Road in a 3rd round cup tie in the 67/68 season, Manchester City were playing Reading. In their time-honoured fashion, City were making a meal of lower division opposition, but finally won a penalty. As these were the days of 'One Pen Lee', the might penalty taker, he put the ball and the spot, and walked back to take his customary enormous run up.
However, unknow to him Tony Coleman, the left wing at that time, decided HE was going to go for glory; as Franny Lee walked back, he ran up and proceeded to belt the ball miles over the bar. Cue collapse of Kippax Stand occupants.
City went on to win the replay 7-0
