Cuba Gooding, Jr. was a human with whom the Jackie Tyler of a parallel universe shared her birthday, 1 February. Gooding, Jr was born in 1968, and Jackie's autobiography claimed she was born on the same day he was. Jackie was actually born a year earlier. (TV: Rise of the Cybermen)
- Gooding Jr. was actually born on 2 January in the real world. It's not certain if the discrepancy is because Rise of the Cybermen is set in a parallel world or because Jackie (or the production crew) forgot that the style 02/01/19XX would be 2 January in the UK but 1 February in the USA .
