A class that begins at 8 AM, also known as the bane of the existence for college students. Classes that begin at 8 AM are pretty much GPA-suicide for any class with an attendance policy. You're either going to miss it, or you're not going to awake enough to function. Especially avoid if it's a science or math class.

Mark:...I'd rather lick a cheese grater.
