Derek and the Broadhill gang go on a trip to London Zoo. It's Derek's best day ever, as he meets giraffes, penguins and aardvarks, while Vicky meets the man of her dreams.

Derek goes on a date with a girl from a dating website. He's excited but he's also worried about his dad's health. True to form, Geoff nearly ruins things for Derek, but Kev stands up to him.
