“[Robert] Kennedy did not just play furiously.  He was furious,” spoiling, off the field as well as on, for a fight – often for senseless fights.  One took place in a Cambridge bar where Bobby, celebrating his birthday with a group of friends, including the football captain, Ken O’Donnell, was picking up everyone’s bar tab.  Another Harvard student, John Magnuson, happened to be already celebrating his birthday there, and his friends began singing “Happy Birthday” to him.  Infuriated over what he apparently regarded as an intrusion into his celebration, Bob walked up behind Magnuson and hit him over the head with a beer bottle, sending him to the hospital for stitches.
