Dunn was the first player in British football to score a golden goal. He achieved this feat in the Auto Windscreens Shield for Huddersfield Town versus Lincoln City on 30 November 1994. Huddersfield won 3-2 in extra time. Dunn was later presented with a commemorative trophy.
Always a cult figure, Dunn polarised fans' opinions; despite this he was voted Huddersfield Town's all-time cult hero by the club's fans in an August 2004 poll for the BBC's Football Focus programme, and he has recently been included in the fans' all-time 100 favourite players.
His cult status amongst Huddersfield fans was often aired with the popular terrace chant:
Iain, Iain Dunn
He's got no hair,
But we don't care.
Iain, Iain Dunn.
Dunn is currently a street environment officer for York City Council. In late 2006, Iain was involved in a national campaign to prevent the people of York putting their bins out too early, a job described as "not glamorous, but...very, very important" by Iain, on a Daily Mail press release. Iain is a Street Environment Officer and this new team, which was set up to fight environmental crime in 2003, has won national awards.
