One day, a very attractive dumb blonde undergraduate visited the professor’s office. The blonde under graduate pulled the chair closer to the professor, smiled at him shyly, bumped his knee “accidentally”, etc.
Finally, the dumb blonde said, “Professor, I really need to pass your course. It is extremely important to me. It is so important that I’ll do anything you suggest.”
The professor, somewhat taken aback by this attention, replied, “Anything?”
To which the dumb blonde undergradute cooed, “Yes, anything you say.”
After some brief reflection, the professor asked, “What are you doing tomorrow afternoon at 3:30?”
The dumb student lied, “Oh, nothing at all, sir. I can be free then.”
The professor then advised, “Excellent! Professor Potter is holding a help session for his students. Why don’t you attend that.”
