The teacher had given the class an assignment. He stressed the importance of it, letting his students know that no excuses would be accepted except illness (with a medical certificate) or death in the immediate family (with a note from that member). A smart-ass student piped up, “What about extreme sexual exhaustion, sir?”

The class broke up laughing, and when they settled down the teachers responded, “Well, then I guess you'll have to learn to write with your other hand!”
