Ben Geller-Willick is Ross and Carol's son, born during "The One With The Birth" but lives with his mother and her lesbian life-partner, Susan Bunch. Ben is played as an infant by Michael Gunderson, by brothers Charles Thomas Allen and John Christoper Allen from Season 3 to 5, and by Cole Sprouse from Season 6 to 8.
Ben is Ross's only son, from his first marriage. He is raised by his mother Carol, and her lesbian life partner, Susan, so Ross only gets to 'babysit' Ben on occasion. Ben is rarely seen with the other Friends, who were present at (or very near) his birth. This causes him to sometimes mix up their names, like calling Rachel Phoebe. The gang all adore Ben, but prove pretty unreliable babysitters, not just clumsy Joey and Chandler (who once lose Ben on a bus while doing his babe-magnet value) but even devoted and domestic Aunt Monica, and Rachel who teaches Ben pranks, of which he pulls on his parents. Being spoiled by three rivalling parents (Ross and his two mothers, Susan and Carol) and bright by nature, cute Ben grows up as an amusing rascal. Although he seems to get on with the other friends as well as his father Ross and Aunt Monica, he was once both bemused and frightened by Phoebe when he witnessed her losing her cool over an arcade game in Monica's flat, but apart from that one incident, there is no evidence of him ever losing any love with any of the friends.
- His first episode is in The One With The Birth and his last in The One Where Joey Dates Rachel.
- It was never shown how they decided on his last name.
- While his parents initially could not agree on a name, they eventually came to "Ben" when Phoebe (while wearing a janitor's uniform with the name tag "Ben") lectures Ross and Susan on how lucky the baby is for having such loving parents.
- When he was a baby, the Allen twins started talking, which caused problems as he had to be quiet in the scene.
- Ben's age is meant to be six in The One Where Joey Dates Rachel, but it was said he was seven.
- Ben is said to have been John Travolta's favorite character.
- Ben's godfather is Chandler Bing as said in "The One Where Rachel Smokes"
- Throughout the show, he never meets his half-sister which dismays fans very much (But maybe he did off-screen).
