ON THE BUSES (1970) Series Three Ep 5 Busmen's Perks
Olive wants to re-decorate her and Arthur's bedroom, so, to do it on the cheap, Stan gets two tins of paint from the depot. They are the bus colours - red and yellow, which Arthur mixes to make green. Unfortunately he omits to add hardeners so that the paint is very, very, very, very, very slow-drying and Olive gets hand prints everywhere.
