The painting above is called "Faith in America" by Donald Zolan. If you want, you can view a print in the main office of Cooper Middle School, or probably any Hobby Lobby or Mardel.
As you can clearly see, the painting subtly portrays two young atheist children sarcastically praying to a Christian god in front of the American flag to appease their mega-controlling Sunday School-teaching parents. It's pretty obvious, right? Only a smartass would be that devout, cute, patriotic and adorable while praying. It has to be some sort of satirical statement against organized religion in America, doesn't it?
