My ex has the same name/phone book listing as a local Sociology professor, we used to get calls in the middle of the night during midterms and finals asking for extensions on papers, test retaking, and general oh-please-god-don't-flunk-me. We used to tell them they had the wrong number and try to go back to sleep...after the umpteenth wake up call of the night one time I just started telling the kids "sure, I'll give you another week on that paper".
