My wife of 14 years is convinced she has Mad Cow disease... ... After all, she had a fast food taco with ground beef last week, and the news reported that the meat from the infected cow had entered Oregon's food supply. "Waaaah!", she wails, wringing her hands. "I'm sick! I can feel it eating my brain already! I'm losing my memory! I can't remember anything!" "But Honey", I try to reassure her, "As far as I'm concerned, you've *always had* Mad Cow disease!" .... She frowns, "Are you calling me mad?" .... "Noooooo...", and then something struck me in the side of the head and the lights went out.
