"A better look at the board" joke
A physics professor was very strict about attendance, and despised tardiness. Every student caught arriving to class late (especially those interrupting his lecture) was quickly reprimanded in front of the whole class. Students were quick to comment on the professor's genetics.
Well, one day a student entered through the front doors of the lecture hall, while the professor was writing notes on the chalkboard. The professor caught the student out of the corner of his eye (this acute sense of peripheral vision, further supported the rumors of his evolution), and turned to face the student. He demanded, "What do you think you're doing?"
Being a science student, one naturally thinks quickly, so the student snapped up and replied, "I came down from the back to get a better look at the board."
The professor smiled.
