Expectant father (One Born Every Minute)

Dawn's husband was a human who had two children.

Dawn was about to give birth with her expectant husband in a UK hospital and called on the intercom for a midwife. Several people entered and gave post-war advice on how to give birth. Dissatisfied, the couple tred the intercom again, this time asking for a Doctor. The TARDIS materialised and the Eleventh Doctor emerged. He warned that the couple's twins Jonathan and Edward would one day grow up to be a most horrifying creature - Jedward. (NOTDWU: One Born Every Minute)
