In a study of 200,000 ostriches over a period of 80 years, no one reported a single case where an ostrich buried its head in the sand (or attempted to do so - apart from Bones ).
Somebody actually conducted a huge study that lasted 80 years, even though it would yield no other benefit than to contradict a few cartoons?
Between 1937 and 1945 Heinz produced a version of Alphabetic Spaghetti especially for the German market that consisted solely of little pasta swastikas.

Sorry. I'm in a bad mood.
