Using a #2 pencil, circle the word in the following sequence that does not belong: "Fraternity," "Sorority," "Serious."It's a trick question. Sadly, they all belong. On college campuses today, undergraduate membership organizations are under an unforgiving microscope. Booze is out. Hazing is out. Inappropriate sexual behavior, of course, is out.Gone, too, is the kind of "involuntary servitude" implied in the command: "Mellman, you miserable worm, get down to Rumplemeyer's and buy me a macaroon."But scavenger hunts?! Boy, when scavenger hunts are out, you know it's serious.The rationale for forbidding them, explains an expert on college-fraternity relations, is two-fold: The hunt might demean the persons compelled to scavange; and the items sought, if inappropriate and later depicted online, might incite outrage ("That's a squirrel's forearm!").
