The Twitterati eagerly patched into the line, after UK Prime Minister David Cameron posted a picture himself, talking to US president Baracak Obama about Ukraine issue.

In a Twitter post Cameron had wrote: "I've been speaking to @BarackObama about the situation in Ukraine. We are united in condemnation of Russia's actions." He put the post, along with a serious looking picture of him speaking on the phone.

Soon after this comedian Rob Delaney chimed in: "@David_Cameron @BarackObama Hi guys, I'm on the line now too. Get me up to speed."

And sice then, the social media has been flooded with Cameron memes. 

Delaney's spoof on Cameron's tweet soon went viral, and people from across the globe joined in, by posting all sorts of pictures, lampooning Cameron.

But there was no stopping, once Sir Patrick Stewart decided to drop in as well. The "X-Men" actor continues to be a show-stealer since his Super Bowl gag. He also had a Cameron impersonation picture.

And then, it started to get a little naughty!

People from across the globe joined in, to ridicule Cameron's social media fail.

And then, it got a little more naughtier!
