On The Buses S03 E05 Busmen's Perks

Stan smuggles paint out of the depot to redecorate Olive and Arthur's bedroom, which Arthur called "unfit for human habitation". He is able to smuggle some paint home, which happens to be green and yellow, the bus colours. A series of mistakes take place during the process: Arthur accidentally forgets to put the hardener in the paint so it takes a very long time to dry, and Olive touches the wall with paint on her hands when going to the toilet in the night.
