### On his first day of classes at...

On his first day of classes at a university, a student took a front row seat in a literature course.

The professor told them they would be responsible for reading five books, and that he would provide them with a list of authors from which they could choose.

Then the professor ambled over to the lectern, took out his class notes and began ... "Baker, Black, Brooks, Carter, Cook ... "

The student was working feverishly to get down all the names, when he felt a tap on his shoulder.

The student in back of him whispered, "He's taking attendance."
