Making the rounds today is this classroom parody of The Office (which itself is parody). Not only does the classroom ring true, in more ways than once, it's also a great example of students exercising their own creativity (in a manner exactly opposite to the classroom portrayed in The Class). Note how one act of creativity uses a prior act as a frame. This is common, and fundamental to creativity. Also, it wouldn't be a YouTube hit unless it was inspired by something people already know.
