To perm or not to perm?

Aaron and I walked by the Greenwood Academy last night on the way to the library. (I had to pick up my copy of "The Game" that I had on hold. More on that another day.) As we passed, we saw this sign.

I turned to Aaron and said, "That is so not true. I like straight hair better than curly."

Aaron said, "I guess I can cancel my perm appointment then."
