I couldn't make this stuff up

From a student of mine:

"It is important to understand the rules and regulations of writing and sentence structure. Communication has always been the cornerstone of our past. Even the men and women who lived in the Crustacean era tried to communicate with each other. Even though to us it may have looked like crude drawings and may have sounded like grunts and groans, regardless of how primitive they were, they must have had their own rules and regulations in order to be understood."

Heeeeee. I guess this is when everyone was pretty crabby.
