LONDON (AFP) - British Prime Minister David Cameron on Friday laughed off the widespread mockery of a photo he posted on Twitter of him looking serious while on the phone to United States President Barack Obama.
In a tweet to actor Patrick Stewart, one of those who had parodied Mr Cameron's photo, the Premier posted a snap of a meeting with former US president Bill Clinton - "this time face to face, not on the phone".
On Wednesday, Mr Cameron posted a photograph of himself discussing the situation in Ukraine in a telephone call with Mr Obama.
His grave expression was intended to convey the seriousness of the subject, but it was mercilessly mocked online.
US comedian Rob Delaney posted a picture of himself looking serious with a tube of toothpaste held up to his ear, writing: "@David-Cameron @BarackObama Hi guys, I'm on the line now too. Get me up to speed."
Stewart, best known for his long-starring role in Star Trek, responded with his own photograph looking serious with a tube of wet wipes at his ear.
"@robdelaney @David-Cameron @BarackObama I'm now patched in as well. Sorry for the delay," the 73-year-old tweeted.
Mr Cameron met former president Clinton at his Downing Street office on Friday, and afterwards tweeted a photo.
"@SirPatStew Talking to another US President, this time face to face, not on the phone," the Prime Minister wrote.
