Allan Partridge - A Comedy Character

i went to see the allan partridge live shop. Allan is a comedy character played by an actor and comedian called steve cugan. The show is called stratagem, which is not a word, is it? Stratag kind of a cross between strategy and something else. It's just that very partridge using a word that people don't actually use any more. But really, he's just trying to sound cleverer than other people by using a quite big sounding word but actually, no one uses it.
