Eric (Sean Penn): Ursula Buffay's boyfriend, whom she brings to Monica's Halloween party in "The One with the Halloween Party" (airdate November 1, 2001; Season 8, No. 6). Phoebe is attracted to him but learns that Ursula has lied about herself in order to marry him, and so promptly warns him about Ursula's lies. He dumps her and in "The One with the Stain" and tries to get together with Phoebe, but cannot stand to look at her as she reminds him of her sister. Phoebe is able to convince him to see past that, and after she leaves for a massage client after their make-out session, she comes back only to find that Eric had sex with Ursula thinking she was Phoebe. They awkwardly decide that it is too weird to pursue things any further. Penn got the role after he made several visits to the "Friends" set with his children, who were fans of the show.
