The prime minister appeared not to welcome the Speaker's interruption as he was mocking Labour's appointment of adviser David Axelrod.
David Cameron told John Bercow that he had not finished, only to be told: "He can take it from me, that he has finished."
It came at the end of exchanges between Mr Cameron and Ed Miliband dominated by the Royal Mail sell-off.
