From Prussia with love. Del arranges to sell the baby to Boycie and Marlene and assures them it's a boy.
Boycie and Marlene come round to the flat to collect and discover the baby is a girl and Boycie says "ain't it typical, everything you buy of him has something missing."
They then discover the baby is brown, Marlene says they could say it's a throwback and Boycie hits back with "For Gods sake Marlene. I might be able to con people into buying cars. I might be able to convince them that you conceived and gave birth in seven days flat, but how the hell am I gonna persuade them that my grandad was Louis bleeding Armstrong!!"
