Ross seems to have a childlike need to always be right.
Such as in The One Where Heckles Dies, when he finds out that Phoebe doesn't believe in evolution.
He has also co-hosted the Academy Awards, Screen Actors Guild Awards, Golden Globe Awards and the 2010 Emmy Awards.
He has also been in several skits on The Tonight Show.
He is the only member of the group of friends with a doctorate and, as such, can be arrogant.
