Ross Eustace Geller, Ph.D., (born October 18, 1967) is a fictional character on the popular US television sitcom Friends (1994–2004), played by David Schwimmer.

Ross is the older brother of Monica Geller, and was often favored by their parents (particularly their mother) over her. His birthday is on October 18 (although in another episode he claims it's in December). When he was born, he was described as a "medical marvel", since his mother was originally believed to be barren. The two siblings are extremely competitive as was demonstrated in 'The One With the Football', where it emerged that every Thanksgiving during their childhood they had taken part in a football match called 'The Geller Bowl'. This continued until one year (Geller Bowl 6) Monica broke Ross' nose, and their parents forbade them from ever playing football again. In their childhood, Monica and Ross were very violent with each other. For example, Monica apparently hit Ross with a giant pumpkin. For his part, Ross once jammed a stick through the spokes of Monica's bike causing her to flip over and hit her head on the curb and jamming a pencil in her hand.

The Geller Yeller

The Geller Yeller, which is only mentioned in one episode, is the Geller's family newsletter that Ross types up. He let that slip to Rachel during one episode when he was having trouble getting to more classes but claims that he already put it in the newsletter. Rachel found it weird and carried on talking as if she hadn't heard anything.
