Extreme Sexual Exhaustion…

A young beautiful lady teacher started talking about tomorrow's final exam in her college class. She said there would be no excuses for not showing up tomorrow, barring a dire medical condition or an immediate family member's death. One smarty, male student asked, ‘What about extreme sexual exhaustion?’, and the whole classroom smiling with looking hither and thither. After a pause, the teacher glared at the student, and said, "Not an excuse, you can use your other hand to write."
