My daughter does them just as I did when I was in grade school. However, the naughtiest I've ever heard was:

Apples on a stick
Make me sick
Make my tummy go two forty six
Not because I'm dirty
Not because I'm clean
Just because I kissed a boy behind a magazine
Hey girls wanna have some fun?
Here comes Johnny with his pants undone
He can wiggle
He can wobble
He can do the splits
But I betcha five bucks he can't do this
Close your eyes and count to ten
If you mess up start all over again
One, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten
Big fat hen!

(During the counting, the clappers close their eyes continuing to clap. If they mess up they start back at one. If they make it to 10 they open their eyes and yell "big fat hen!")

I can't believe how little innocence is left among our children. Especially with a chant like "Shame". It's sad really.
