I've got you beat by far, wsf99!
Fall semester sophomore year (Fall, 2001), I overslept for a FINAL EXAM, missing the ENTIRE exam! I ran to the classroom to see if the professor was hanging around, to no luck, so I walked back to my dorm with an empty feeling. I call his office and get no answer, so I left a message on his voice mail...I got a reply about a half-hour later.
Fortunately, I had only missed a couple classes over the course of the semester, so he held great compassion for me, allowing me to take the final two hours later! I got an A in the class and thanked him dearly!
