Jack and Erica were born in the series finale. Monica and Chandler were unaware at the time of their birth that they would be receiving twins and Monica had to calm Chandler down at first. Upon seeing Jack for the first time, Chandler commented that he had Monica's eyes (despite acknowledging that it was impossible for this to actually be the case).
- According to Monica in "The One Where Rachel Has A Baby, Part 2", she had wanted to name her future son Daniel. However when she did have a son, she named him Jack.
- Jack was the first of the twins to be born.
- Jack Bing would be 16–17 as of 2021.
