The latest strain of influenza, with a little Swine Flu, Avian Flu, and Human Flu all thrown in ... you get a piece of everything ... just like turducken
(the holiday melange of a chick stuffed in a duck, which is then stuffed in a turkey). Sliced just right, you get a piece of everything.
"I thought it was the regular flu, but my hair hurts. I think it's the Turducken Flu."
