Two great rivals, one red, the other blue, in yet another titanic clash, one which neither can afford to lose...
The wider the grin, the less Mr Brown likes it
Oh, and apparently there is a football match on today as well.
OK, Prime Minister's Questions may not quite beat the Champion's League Final for glamour and drama, but it did have its moments.
As might well be the case in Moscow tonight, there was a cagey opening.
David Cameron started on Burma, trying to gently edge Prime Minister Gordon Brown towards the idea of dropping aid to the victims of Cyclone Nargis, with or without the permission of the authorities there.
Equally gently, Mr Brown ruled nothing out; and then explained why he would not be doing any such thing, at least in the near future.
When his turn came, Nick Clegg, the Liberal Democrat leader, called for a defence review which would give our troops the equipment they needed for conflicts like Afghanistan.
The prime minister told him it was pretty much happening already.
But with polling day in the Crewe and Nantwich by-election less than 24 hours away, David Cameron decided to go for the win.
He taunted the prime minister about the 10p tax row and asked why, if his compensation package was for the long-term, he had not joined the campaign to explain it to the voters there.
Mr Brown claimed there was a convention that prime ministers did not get involved in by-elections, only to have the words of one T. Blair thrown in his face by a gleeful Opposition leader, who had apparently promised to lead from the front in a previous campaign.
You can tell how much Gordon Brown hates something David Cameron says by how much the prime minister grins when he says it.
After that exchange, Mr Brown was grinning a lot.
You can stretch an analogy too far, but if the outcome of today's PMQs is replicated in faraway Moscow, the Brits in the blue Cossack hats will have a lot more to smile about than their rivals in Red Square.
Here are the key points from prime minister's questions:
