Yale's pansy students and pantywaist administrators decided political correctness had to win out over humor, college rivalry, and literary reference. They banned T-shirts quoting F. Scott Fitzgerald, "I think of all Harvard men as sissies."
I guess they were worried that Sissy-Americans (or is it "courage-challenged"?) would be offended to be associated with Harvard.
If churning out douchebags like John Kerry and George W. Bush is not enough reason to keep your kids far away from Yale, this ought to be.
