states that she is twenty-nine, placing her birth in approximately 1968. However, in "The One Where They're Going to Party" (Season 4), Ross states he is also 29, which does not work with the previously mentioned two-year age gap. According to "The One with Frank Jr.", Phoebe was born on February 16; however, in Season 9 ("The One with Phoebe's Birthday Dinner") Phoebe's birthday is sometime in early November, since they could not make the reservations and the dinner had to be moved back to October 31. In "The One Where They All Turn Thirty" (Season 7), it is revealed that Phoebe was born a year earlier than she thought, believing she was 30 but was truly 31, which further adds to the inconsistency of her age throughout the show's run.

She also used her fake name to show Chandler and Monica how easily people lie about their names and to help Chandler with his interviewing skills in season 8 episode 4, when Joey says, "Hi, I'm Ken Adams" she replies, "Regina Phalange".

She immediately switches to French and claims that Joey is her younger brother who is "un peu retardé" (a little slow), and requesting that the casting director humor Joey's French-speaking abilities. The last reference is in the series finale when Phoebe successfully stalls Rachel's plane to Paris by saying there
