Though you may have trouble with a school board passing this script.  It does have some jokes at different religions and comments about getting drunk.

 

We actually did the show with 30 kids and it was amazing.  Our leads were almost all over 13 and Evan's music was transposed for a couple of songs to get it in his range but it actually worked very well as Brett was played by the oldest boy which gave the illusion of a held back dumb jock and Evan was played by a 15 year old but he is small for his age but his voice had changed to a Bari-Tenor.  He sang his full range and even had to go into his falsetto for a few notes.  We had a large ensemble which was great for the group scenes.

 

It was received very well by the audience and we sold out all 4 performances. People thought it was exceedingly funny and did not seem offended but we did put a PG warning on our advertisement.  Though it reads offensive it really doesn't come off that offensive if you stage it right.   We did drop the tampon machine/candy machine joke as we had no way to have one on the wall and the director thought it just pushed the envelope on offensive.  We are a small blackbox theater so our set was murals painted on the walls and some chairs and colored cubes but the kids, blocking and lighting created each scene.  Here is a link to a picture in our university paper.
