Janey's baby is due in Manchester. Susan rings Janey to support (or rather annoy) her. Janey hangs up mid-conversation and then doesn't answer the phone. Susan is convinced Janey has gone into labour. A reluctant Ben is frog-marched to the car for the long drive north.
During the trip Ben and Susan have flashbacks to Nick's birth. They were getting ready for an evening of 70s disco dancing when Susan went into labour. During the dash to the hospital Ben felt The Stranglers's Peaches was the perfect mood music - until Susan threw the tape out the window. Things got even worse when the petrol ran out and Susan was forced to push the car.
Back in the modern day it seems like history is repeating itself. The car has once again run out of petrol. At a service station a starving Ben has also managed to smash up a sandwich dispensing machine. Not only does he have to pay for damages but his sandwich now has glass shards in it.
Another flashback to Nick's birth sees Susan having last minute jitters. Now she's to be a mother her dreams of going to the Galapagos Islands are fading fast. They imagine that their new son will have a brilliant career but feel sad that in just 18 years he will move out of their lives. Little do they realise...
Meanwhile Janey has phoned - she is indeed in labour and gives them the name of the hospital. However Janey hangs up when Susan reveals they are in the car on their way to Manchester.
Back in the 70s, the first Harper son has been born. Ben and Susan go through likely names - Peter, Adam, Robin, Mark, David, Steven, Pegasus - all of which are dismissed by Ben. They decide to name him after the next person to come into the room, who happens to be 'Dr Bumface'. He explains that it's a nickname.
Finally arriving at the hospital Janey has already had the child - a boy. As Ben and Susan hold him he has a couple of 'accidents'. They spend the rest of the evening sitting in the laundrette.
