No worries, Max.

When I was in high school, we had a teacher, Mr. Little (real name), who was also in charge of an "Enriched Math" class.

He came to my desk and showed me my exam mark: "U" {Unsatisfactory}. He pulled my hair and said abruptly:

"You're too stupid to be in my Enriched Math Class."

Imagine a teacher saying this in today's politically correct world?
