I really like to swim,
but the chlorine doesn't kill the germs instantly.
I really wanna swim,
but I need to make sure it will be healthy.

Yeah, I'm chillin' by the pool side,
bout to make a splash with my cool rhymes.
Here's a message from the CDC, please hear me,
tell you a little about the healthy
swimming program, listen to my flow man,
just trying to keep you safe while you're floating.
Protect yourself from RWI's, what's this?
Recreational Water Illness.

When you're swimming keep the water out your mouth,
It's filled with germs, so you need to keep them out.
One more thing that I need to teach ya,
never swim if you have diarrhea.

I really like to swim,
I really like to swim.
