Classroom Retardation

Retard
Don't be like this guy.

When you raise your hand in class, do not say:

"I just wanted to say that..."

Just say it. Maybe even compliment the person that you're cutting off by asking a stupid question or seconding an opinion.

"That raises an interesting point. I too think that sea snails in the North Atlantic Ocean can tell us a lot about the price of coffee in Argentina."
