Are You Being Served?, Season 4

Mr Humphries:
[To his mother, on the phone] If a man rings up with a Scottish accent, you're the cleaner and you've never heard of me. No, I don't owe him any money...I don't owe him anything. What do you mean there's someone coming up the garden path in a kilt? Well, look, lock the door and hide in the cupboard. I'll phone you before I leave here. Whatever you do, don't open the door unless it's a young policeman carrying a rolled umbrella. And if I can borrow a helmet from the toy department, that'll be me."
