ISIS claim responsibility for London attack, and everyone is making the same joke

ISIS have claimed responsibility for yesterday's attack, saying the perpetrator was a "soldier of the Islamic State”.

But people on the internet are skeptical, and everyone is currently on twitter making the exact same joke, that ISIS would claim responsibility for every bad thing in the world if it made them look even a tiny bit like the bad guys.

They're coming in at the moment at roughly five a minute, but here are some of the better "ISIS claimed credit for" jokes we've found so far.

And personal favourite...

So far, there has been no confirmation from anybody about the claim made by ISIS. But it's nice that we're already taking the piss out of them.
