Mr. Cosplay
The grand actor has arrived! What better way to give a history lesson than to try to set the mood of the times and recreate the scene. This teacher just so happens to have a knight costume to sport while giving lessons on medieval history. This is definitely one way to capture the attention of his student.
We wonder if he has a costume to wear when presenting other periods of history as well. This gives us the impression that this teacher has a secret passion for acting Perhaps he can join the drama department.
