Keeping up the tradition of posts that contain interesting but ultimately useless facts and information, I have this to add:A duck's quack does not echo!
I do not know who engages in this kind of scientific enquiry and the importance of knowing such information. Nevertheless, who am I to judge such endeavours?
Someone should update the questions on trivial pursuit because I am sure to be a legend in my own lifetime :D

Who told you that? Any sound will make an echo under the proper conditions.
I will happy to demomstrate if you provide the research funding.
Finally someone has challenged, I was going to ask "prove it" over a scotch and or red wine some day.
Finally busted...
The factoid was taken from a questionable source; the underside of a bottle cap :D
However, as PJB has pointed out, under teh right conditions a duck's quack does in fact echo. The echo though remains faint but nevertheless the urban legend in this case has been proven false.
See this link, http://www.sciencemadesimple.co.uk/page29g.html, for further details as to the fallacy of the non-echoing duck quack.
