Continuity: Ross's birthday is inconsistent. In "The One Where Emma Cries" Ross says his birthday is October 18th. In this episode (which aired October 19th), Ross is taken to the Hootie and the Blowfish concert on his birthday. However, in "The One with George Stephanopoulos", Joey and Chandler buy Rangers' tickets to celebrate Ross's birthday on October 20th, and Ross says that his birthday was seven months ago, implying his birthday is in March. Furthermore, in "The One with Joey's New Girlfriend" Ross tells Gunther his birthday is in December.
