We know that Dara Ó Briain has plenty of Twitter followers and a razor sharp wit, so trying to troll him is always a bad idea.
Recently, in a discussion about the Irish being different from the English, he started getting abuse from a Twitter user with a rather rude name, who tried to convince him, a gaeilgeoir, that the two were pretty much the same, just like any other "English speaking country". He decided to differ, and gave a pretty fantastic response.

As John Moynes pointed out though, he didn't use the fadas so we'll have to dock him marks for that.
