President Barack Obama will today let David Cameron play with his Lego and possibly have a go on his Nintendo DS.
Already Cameron has had a ride on Obama's aeroplane and has been to a basketball game where he was allowed a hotdog.
A US government spokesman said that Obama was determined to give Cameron a good time during his visit.
'He's a good boy,' the spokesman said, 'and is being rewarded for sending nasty boys who mess about with our computers, like Richard O'Dwyer, to us.'
'David is enjoying his holiday in America,' said Downing Street. 'He is keeping his fingers crossed that he may even get a surprise visit to Disneyland.'
