The prime minister has suggested a new hand gesture for the shadow chancellor, who regularly taunts him at PMQs.
David Cameron broke off from reeling off a list of government actions, as Ed Balls pointed downwards, to say it "should be bye bye".
And the PM told Ed Miliband he did not need it to be Christmas to know he was "sitting next to a turkey".
