Re: Crows

["Jerry Cohen" <jjcohen@PRODIGY.NET>]

Once upon a time a wizard hypothesized that white crows exist. To test his

hypothesis he gathered a million crows from all parts of the world and

carefully examined them to assess their color. All of the million crows were

black. He concluded that perhaps his sample size was too small; white crows

might  actually exist and it was therefore prudent to maintain all the laws

in the kingdom that presumed existence of white crows.
