You've got to love the BBC's imagery in their Q&A for the current swine flu break out that is all over the news.
First they kindly depict the 3 different types of flu...

Then they detail antigenic drift and antigenic shift (slide 2) and then slide 3 has this picture...

Hmmmm.... bird flu + swine flu + human flu = flying pig with a running nose?
Or more precisely...

That didn't take long.
