Man bumps head, crowd goes “ooooh”… 

Much of the Olympic Games takes place in the swimming baths. There’s the 100 metres Butterfly, synchronised swimming, bombing, petting, ducking, and, of course, diving. Back in the 1980s when absolutely everything was neon, one man ruled the boards - Greg Louganis. He’d taken two gold medals at the Los Angeles Olympics in 1984, and in 1988 he managed the feat again, but not before enduring an almighty wallop in the qualifiers (above). Ouch, Greg!
