A pretty impressive April Fools Day Prank

Two Yale students from the Class of 2005 played an impressive prank on Harvard. Disguised as the "Harvard Pep Squad," they and 20 classmates handed white and crimson signs to fans in the central area of the Harvard side of the sport stadium. The pranksters told the crowd that by lifting the signs they would spell "GO HARVARD", but the signs were actually arranged to spell "WE SUCK".
