Grammar fun

As a bona fide grammar nerd, I regularly read the “Grammarly” blog.  This week’s blog had some entertaining sentences, one of which was:

“The man the professor the student has studies Rome.”

This sentence conveys that the student has a male professor who studies ancient Rome.  The embedded information in the center of the sentence is grammatically correct, but confusing.  Given the fact that this is a grammar blog, I couldn’t help groaning at a reader’s comment that asked, “Haven’t you heard about comas?”

What makes English grammar fun?  The fact that the following sentence makes sense!

“All the faith he had had had had no effect on the outcome of his life.”
