Well, Charmion and Sandra, I can top your black eye stories.
Back in the year 2000 I was attending a friend's 50th birthday ball (at Bundanoon, Sandra - she lived in Canberra, so it was convenient for her south coast, Sydney and Canberra friends) and one of the dances on the program was 'Postie's Jig'. Being a Scottish dance it ended with a Scottish swing - left arm around partner's waist, right arm held curved in the air while swinging. As one of the women in our set flung up her arm she connected with the bridge of my nose.
I saw stars, let me tell you. Didn't fall down, but....oh geez, it hurt.
The result was two black eyes. Yes, two. At the same time.
