They were foes across the Dispatch Box but George Osborne appears to be missing Ed Balls.
The Chancellor going toe-to-toe with the former Labour MP was a regular highlight in Parliament.
But after Mr Balls was ousted at the election, he was replaced as Shadow Chancellor by his deputy, Chris Leslie. The Chancellor appears to think this does not pass muster.
During Treasury Questions today, Mr Leslie asked twice about the UK economy's struggling productivity and why Mr Osborne would not be fronting a debate on the issue (he is in fact on Prime Minister's Questions duty).
"I never thought I'd say bring back Ed Balls, but ...," he said to raucous laughter.
"I think the Labour Party needs to look at the productivity of its own front bench after those two dismal questions."
During the session, the Chancellor struck a more sombre tone when he warned of the "economic risks" posed by Greece potentially defaulting on its debts.
"Out there in the real world there are some very serious economic risks," he told MPs. "Not least the risk we now see in Greece of a potential default and a potential exit from the euro.
"People should not under-estimate the potential damage that would do to financial confidence."
