I remember a scene in an episode of Fawlty Towers when Basil, frustrated as usual, frowns and shakes his fist threateningly at a garden gnome.

In another episode, he is going to "insert" a pointy-hatted gnome into Mr. O'Reilly, a contractor that's responsible for messing up a project and bringing down the wrath of Mrs. Fawlty on him.
