"For the two years I was there, it was hard to get close to Clemente. He would be invited to parties after games, but never attended. But it’s not like he disliked his teammates. And he showed a good sense of humor in the clubhouse – hiding your shoes or playing other practical jokes. Joe Christopher was one of his targets. But Joe was kind of easy to egg on. [...] For the time I was there, Clemente and Murtaugh got along very well. Of course, I was there at a very good time – in 1960 when we won the Series. Everybody got along then. There might have been a few harsh words between players once in a while, but no major problems."
