For me, the finish of the 1988 Worlds springs to mind. It looked like cheating but it probably wasn't. A lot of people thought - at least at first - that Bauer had run Criquielon into the barrier deliberately. But then you only had to watch the way Bauer's whole thang collapsed to let Fondriest almost freewheel past to realise it was probably unintentional. It could have been a Hand of God moment but instead it was actually more like a 'I did not have sexual relations with that woman' moment.
