More grammar jokes

Today in Spanish, we were going over a worksheet. Some girl had to fill in the blank with the correct form of a verb. She conjugated it wrong, so the teacher was asking what the subject of the sentence was. One of the questions she asked was, "Can 'no' be the subject of a sentence?" I started laughing like crazy. Of course. "No" was the subject of the interrogative sentence she just said. Bahahaha!
Oh my, I'm a nerd.
