Last week, during the leader's debates, we heard a lot about the various people Mr Cameron had meant. There was much amused twittering about his anecdotage. (Not that he was entirely on his own with this rhetorical strategy.)
You can imagine that his advisers might have mentioned it after the event. That seemed a little forced Dave. Or maybe they didn't. And maybe after the heat of battle has faded it didn't seem so bad again. Maybe worth trying it again next time.
And then the David Cameron Anecdote Generator arrived. Very clearly and virally pointing out what he was doing. I think it's possible, that even though most people in the country haven't seen this, it'll have a nagging influence on strategies for the debate. How can you persist in a technique which has been so thoroughly skewered? We shall see.
