Lyrics:

(Verse #1)
Tyrone:
There's something in the air, and it doesn't smell so good
I wish I didn't have a nose, I'd remove it if I could

Uniqua:
You're not kidding, it smells real bad, it's a really awful smell, the swamp is super stinky...

Pablo:
And I don't feel so well!

Uniqua:
Well, we gotta get this message through and to the other side
There's only one thing we can do, hold your nose and say "P.U.!"

(Chorus)
All: P.U.! Look out! P.U.! Watch out! P.U.! Better jump! P.U.! Sure is stinky!

(Verse #2)
Uniqua:
Never smelled a smell like this, it's like a hot dog rotting in the bun
Or like the smell egg salad makes when it's left out in the blazing sun

Tyrone:
Don't let the bubbles get you, or you'll be stinky, too
And nobody that you know will wanna be friends with you

(Chorus)
All:
P.U.! Look out! P.U.! Watch out! P.U.! Better jump! P.U.! Sure is stinky!

(Verse #3)
Uniqua:
It smells like garbage!

Tyrone:
Like dirty diapers!

Pablo:
Like moldy cheese!

Uniqua:
Like mushy peas!

Tyrone:
Like dirty socks!

Pablo:
On monster feet!

Uniqua:
Or 67-day old meat!

(Chorus)
All:
P.U.! Look out! P.U.! Watch out! P.U! Better jump! P.U.! Sure is stinky! P.U.!
