Well I wouldn't call this embarassing, but its something I dont want to remember, Playing footy with another school it was cup semi final and it went to PENS, but our keeper got injured during the first penalty and had like a fractured finger, then someone had to go in and I offered to go in goal, first two PENS were ok one was missed and the other went in, then this guy came to take a penalty and put full power, I dived to the right and it hit me in between my legs. It really hurt badly, I couldn't continue, then after we win on penalties, But after that I never went in goal again. Probably the painfullest day of my life up to date, though this was about 3 years ago.
