Surreal, joyful, poignant, and peppered with Karl’s trademark wit and comic philosophising, series 2 plunges us further into the world of the lovable loser with a weakness for biscuits. When his elderly aunt Norma hires a young sparky care worker – Ruby, Karl feels pushed out and embarks on some soul-searching. He comes to the realisation that he needs to do more with his life and tries to overcome his low self-esteem and anxiety issues to better himself, upgrade his career and find love – invariably failing miserably.
