Talent show

Okay, from the top: I belong to this thing at my school called GIRLSS Group, which hangs out with junior high girls twice or thrice a month, and we put on a talent show each year. I decided I want to sing a P!nk song this year, and a couple of the girls want to sing with me. Which one should I pick?

And yes, everyone is hypersensitive about swearing, dirty jokes, etc., around the girls. And I know they'll have their eyes on me after I told a dirty joke at last year's talent show, and I'm slightly more lax than everyone about swearing and talking about things others consider "inappropriate" in front of kids. Right now I'm trying to sort the P!nk songs I have on my computer into "appropriate" and "inappropriate," and haven't gotten much of a chance to think about them aesthetically. Which ones would you recommend for three young amateur female vocalists? By the way, I am only considering songs from I'm Not Dead and Missundaztood.
