Joke: "Sleep Talk"

The old horse called out his first girlfriend's name several times in his sleep, and his wife pushed him awake and asked him warily: "Who are you calling?"

Old Ma busy cover up: "I dream of being a teacher, asking students to answer questions."

The wife asked, "Then why do you always ask the same student to answer questions in one class?"

The old horse was stunned and then replied: "Because I am a tutor."
