The 2004 Harvard–Yale prank was a practical joke performed on November 20, 2004, at the annual Harvard–Yale football game in which Yale students, costumed as a Harvard “pep squad”, perpetrated a card stunt. They gave out placards to a section of Harvard fans which, when raised together, read “WE SUCK”.
The stunt was conceived and coordinated by Michael Kai and David Aulicino, two Yale students in the class of 2005, and was executed with the help of 20 classmates. Disguised as the “Harvard Pep Squad”, the perpetrators handed crimson-and-white placards to fans—mostly Harvard alumni, with a few faculty, students, and others—in the central area of the Harvard side of the stadium. The group told the crowd that by lifting the placards they would spell “GO HARVARD”.
Most Harvard students, sitting in a section off to the side of the alumni area where the prank was executed, left the stands unaware of the prank; however, players on the field did see the placards. Harvard won the game, 35–3
