Yes, he was in episode 6 of season 9, "The One with the Male Nanny", as the titual male nanny (or as the guys call him, the manny).

I have to start off by saying that there probably aren't many younger audiences that are watching Friends, since it is a TV14 show. However, I would say that for those who are part of a younger audience that did watch the episode, they probably felt that having a male nanny is unacceptable, as Ross did firmly believe that they could not have a male nanny for Emma because it was unnatural.
