"I remember when Rod Laver was nominated as having 'the most perfect bottom' by the Gay Men of Australia.

I believe Sir Malcolm Sargent won it the year before."

Unfair! If you're in the audience you could see Rod's bottom only some of the time but you could see Sir Malcolm's all of the time (unless you were in the cheap seats behind the band). We need to adopt an objective standard for bottom-observation. I'm willing to take on half the job (i.e., one out of two genders, not one out of two buttocks).
