Kenyan left-arm spinner Aasif Karim, who also represented his country in the Davis Cup, was 39 when he caught the eye with those 50 magical deliveries, tying famed Australian batsmen into knots in Durban in 2003.
He had quit cricket after the 1999 World Cup in England but returned for the next edition in South Africa, showing what players from non-Test playing nations were capable of at cricket's showpiece event.
Karim's victims included Australian captain Ricky Ponting, Darren Lehmann and Brad Hogg. He did not taste success after his heroics, going wicketless against India in the next game, which turned out to be his last one-day match.
Players from so-called minnows may quake at the prospect of facing pacemen Dale Steyn and Mitchell Johnson or bowling to Rohit Sharma and Chris Gayle.
But the giants of the game should under-estimate the minnows represented in Australia and New Zealand by the likes of Afghanistan, Scotland and the UAE at their peril.
Previous World Cups are full of examples of players from smaller sides who have enjoyed a rare moment in the sun such as Canadian John Davison, Kenyan Maurice Odumbe and Irish brothers Niall and Kevin O'Brien.
Davison overshadowed batting greats for a day when he smashed the then fastest World Cup hundred, off 67 balls, against the West Indies at Centurion in 2003.
New Zealand were to suffer next from Davison's punishing blade as the Canadian hammered a half-century off just 25 balls against an attack containing quality pacemen Shane Bond and Jacob Oram.
Ireland's part-timers made history on St Patrick's Day in 2007 when they knocked out former champions Pakistan in the first round with a three-wicket win, their stars being paceman Boyd Rankin (3-32) and Niall O'Brien (72).
