Rio 2016: Eric 'The Eel' Moussambani and the 100m heat
Equatorial Guinea's Eric 'The Eel' Moussambani had never seen an Olympic-sized swimming pool until he turned up at the Sydney Games in 2000. He would leave a legend with a new nickname - winning his heat in a very slow time of one minute 52.72 seconds after the only other two competitors were disqualified for false starts.
