FUN WITH WORDS
Jack and Jill were in English class, when the teacher posed a question the answer of which was either "had" or "had had", as in "I had had a good time but it came to an end when I puked on myself."
Jack, while Jill had had "had", had had "had had". "Had had" had had a better effect on the teacher.
