Jim Callaghan never actually said "Crisis, what crisis?" The phrase was invented by a headline writer, but it was irresistible and Callaghan was stuck with it for good.
A screen grab from the game
Similarly, Jack Straw never punched Ed Balls (and no one ever suggested that he did). But this is another myth that is developing a life of its own and now it has been immortalised by the Tories as a computer game. You can play it here.
It went up on ConservativeHome today. Some of the reaction is very hostile, but the Tories are quite proud of it. They tell me that by around 4pm today 2,000 people had "smacked" Ed Balls, whereas Gordon Brown has only had 3,000 text message responses to a party political broadcast he did earlier this week.
It will be interesting to hear David Cameron asked about it when he's next doing something on violent video games.
But the Tories are unrepentant. "Online is where the political battle is taking place and it is only right that we should be using this medium," a spokesman says.
In truth, I can't believe there are any votes in a game of this kind. And, if this is the future of political campaigning, God help us all.
I suppose I should condemn is as puerile. But actually - I found it quite fun.
