No keys? No problem!
At first glance, this picture looks like a professor who’s teaching his students a little lesson on coming late to class. If you can’t come on time, then you need to find a spot on the sidewalk to listen. Our professors during our college years were crueler than that.
However, this isn’t actually a form of punishment. In fact, it was the professor who made the mistake here. He forgot to bring the keys to his classroom, and since he couldn’t reschedule the test, he had to make do of the situation. This still looks like a lot more fun than sitting inside of a boring classroom all day.
