Really?? Really??? So sad that this country (or is it the whole world) has come to this. Students need to be prodded by the lure of extra credit to go on a date. On both sides of the issue, most don't get the extra credit because it's so 'counter-cultural', but by the same token the professor is going to a wedding soon between two former students who met by fulfilling the extra credit assignment. Sad, so sad.
