"Keep counting the ducks" ?
You would not want to if you were West Indies cicketer Courtney Walsh,
He was out for a "duck" 43 times

Of course Don Bradman was out for a duck in his last innings.
In the Navy, if you were easily fooled,
you were referred to as a "wood duck"
The term is a shortening of the term "duck's egg", the latter being used long before Test cricket began. When referring to the Prince of Wales's (the future Edward VII) score of nought on 17 July 1866, a contemporary newspaper wrote that the Prince "retired to the royal pavilion on a "duck's egg"".
The name is believed to come from the shape of the number "0" being similar to that of a duck's egg.
