Sometimes flus are Asian
(So I've heard)
And sometimes flus are avian
(From a bird)
But when they get mutated
(And they do)
Wreak havoc unabated
(What a flu)
H15N virus, avian Asian influenza
(It's the bird flu)

Back in 1918
(Long ago)
Before there was a vaccine
(Oh, don't you know)
The flu was epidemic
(Spread worldwide)
We couldn't really stem it
(Stem the tide)
1918 Spanish flu killed over 20 million
(Yes, a bird flu)

Hey, Bird Flu, from a goose or a quail
Hey, Bird Flu, we're hot on your trail
Bird Flu, hold off until I
Get some antidote

Hey, Bird Flu, get away from my shores
Hey, Bird Flu, stay in ol' Singapore
Bird Flu, please wait until we get a little vaccine cloned

Bird flu's kinda vicious
(It can kill)
It could become pernicious
(What a thrill)
When people sleep with chickens
(With their birds)
Infects 'em and it sickens
(Worse than GERD)
These viruses are prone to jump from birds right into humans
(It's the bird flu)

Hey, Bird Flu, from the eggs to the chicks
Hey, Bird Flu, you mutated too quick
Bird Flu, my government's got
Just the plan for you--

Hey, Bird Flu, stay away from my lungs
Hey, Bird Flu, go sic William Hung!
Bird Flu, I'm eatin' Spam and stockin' up on Tamiflu!

(Spread the word....it's from birds.....)
