"itty bitty baby" heard in Texas (that was back in 1950s, no idea what they are called nowadays).

Like Leeneia, I diagrammed sentences in junior high (7-9), forget which one. Also not in a Catholic school. We were sent to the 'board, eight or so at a time, and given a sentence to diagram. The one to complete the diagrammation first ended the heat. After the heats, the winners squared off (I kid you not!).
No way I could do it now.
