Crash Course - Any Questions?

During these classes, whenever Mr. Kent asked us if there were any questions somebody would usually ask about a subject not relating to what we were learning. In many cases it was actually pretty funny, but it made the classes longer because we weren't focusing on the textbooks we had to read.

I'm still not sure why Trav cared to know his horoscope. Maybe he was trying to find some type of compatibility within the classroom.
