Ben is Ross's only son, from his first marriage and divorce. He is raised by his mother Carol, and her lesbian 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.
