As an equation for perhaps the most strange and bewildering wicket in recent Ashes history, this probably takes some beating...
Possibly the worst delivery of Graeme Swann's international career + an inexplicably poor swipe and miss from an accomplished batsman + a horrendous decision from the umpire + an ill-advised walk when a review would have overturned the call = a bizarre dismissal.
Chris Rogers was the batsman in question, and he will likely have never walked off a cricket ground feeling as bemused and frustrated in his life.
As Swann himself said after the day's play: "It was truly awful cricket - I never want to see it again. It was definitely the worst ball I've ever bowled."
Cricket writer and comedian Andy Zaltzman tweeted at the time: "Can anyone think of a more error-strewn single delivery in cricket history than the one with which Swann dismissed Rogers?"
Answered simply, no.
Every bowler knows that any wicket is as good as another, but if ever Swann were to be embarrassed to send a batsman back to the pavilion it would have been in this case.
The spinner's delivery looped up inviting a slog for six in the manner of a part-timer down the village green, only for Rogers to unbelievably miss the ball entirely, inviting the gaffe-prone umpire Morais Erasmus to raise his finger.
It may have been an absurd decision, but to not review the call was quite ridiculous. To compound Rogers's misery having walked away, Australia's two reviews were squandered by Shane Watson and Phil Hughes anyhow.
It was, very possibly, the most bizarre Ashes dismissal in memory. England did not complain.
And the reaction from the furious batsman...
And the rather sheepish bowler...
