I've noticed a continuity error!
I was watching an episode earlier on UK Watch and noticed a continuity error, it was in the episode where Ben goes on a date with Susan's friend to make her (Susan's friend) husband jealous
anyway, it is 'revealed' in that episode that the Harper kids were named after Susan's ex-boyfriends but it was at that moment that I remembered the episode where Janey gave birth to Kenzo and Ben chose the name 'Nick' when that man said it was a nickname!
