Torvill and Dean
they had already won Olympic Gold earlier in 1984, at Sarajevo, with perfect scores for artistic performance
on this day day the same year in Ottawa, in the World Championship, in what was then believed to be their final performance, they against scored 9 perfect sixes on artistics performance, and with the four for technical performance on this free dance, became the first to ever score 13 sixes in one competition.
It is arguable that they should have had all 6s for technical, although some judges did not like the one lift. It may be arguable that their Olympic performance was better.
Be that as it may. This is style perfection.
Simply watch - Jayne Torvill and Christopher Dean, the greatest ice dancers ever:
