Prime Minister Tony Blair has said that his children were delighted when he made a guest appearance on top cartoon The Simpsons.
"It is about the only thing I have done that any of my kids have considered worthy of comment," he said.
The prime minister was speaking to pupils on a visit to a school in north London on Thursday.
He added that Leo - his youngest son aged four - had no idea what his father did for a job.
"The kids just think of me as dad," he said. "But my little one does not know at all."
He told pupils that he enjoyed his job, adding: "You have good days and bad days, like everything else."
The Simpsons episode featuring Tony Blair was shown in the UK in January.
