Series:Probability Zero

For those that don't know what "Probability Zero" means, here's what Harry Harrison said in the John W. Campbell Memorial Anthology:

"In the early 1940s, in Astounding, there was a small department called Probability Zero! that ran short-short stories. Or items. Or lies. Things. These things were usually funny and always impossible - echoing the description of the title."

This seemed to be such a good idea that it lasted a bit longer than the 1940s did.
