S1, E6: Flood

Available on iTunes
During heavy rains, London floods and the Young Ones are trapped in the house. When they embark on a game of hide-and-seek to pass the time, Mike finds a lion tamer in his bedroom and Vyvyan hides in wardrobe and enters Narnia. But the sharks at the window and the arson attack on Rick's bedroom pale into insignificance when their landlord Jerzei Balowski turns into a homicidal, axe-wielding maniac.
Starring Ben Elton
