What Happened to Miss Mary Mack?

Today, I was listening to some of the girls in my class sing this hand clapping song:

Hey Mr. Booty
Here comes a girl with an African Booty.
She can do the pom pom.
She can do the twist twist.
But most of all she can kiss kiss like this.
(Proceeds to do the splits as they spell kiss.)

It's all sorts of not P.C. I was so surprised. I told my hubster about this rhyme. His reaction:

Hubster: Did you teach them that?
Me: No!
Hubster: Then what the heck would make you think to think of that?
Me: (LOL)
