The non-echoing duck quack has finally been tested and proven wrong here
FINALLY!
Now I can get some rest.
I learn something new every day…and thanks to kferr, I’m slightly less ignorant this morning than I was last night.
What a way to start the week. 
This OP beat that of [catharsis] by six minutes. At least [catharsis] acknowledged Cecil’s previous research in this area.
Someone call the good people at Snapple.
Oh, my dear Og. I’m sleep deprived. I looked at the thread title and metally started singing:
“quack quack, fizz fizz, ooooh what a relief it is…”
Damn cats kept me up again.
Well yeah but…Cecil did it first.
I’ll sleep a lot better tonight.
