Benjamin Hobart (Greg Kinnear) - Introduced in "The One with Ross' Grant" (Season 10, 2003) as a Nobel Prize winner paleontologist and ex-boyfriend of Ross' girlfriend Charlie Wheeler. He sees her again for the first time in quite a while while she's on a date with Ross, who bemuses both him and her with daft comments in the following conversation. Eventually, Benjamin confesses to Ross he's still in love with her and then unsuccessfully tries to persuade Ross to break up with her, and eventually comes to resent him, asking ridiculous questions at the grant interview just to spite him. He and Charlie eventually get back together, after Ross makes him confess his actions in front of her.
